Boehm, Philip;Roediger, Sven;Bismuto, Alessandro;Morandi, Bill published 《Palladium-Catalyzed Chlorocarbonylation of Aryl (Pseudo)Halides Through In Situ Generation of Carbon Monoxide》 in 2020. The article was appeared in 《Angewandte Chemie, International Edition》. They have made some progress in their research.Category: esters-buliding-blocks The article mentions the following:

An efficient palladium-catalyzed chlorocarbonylation of aryl (pseudo)halides that gives access to a wide range of carboxylic acid derivatives has been developed. The use of butyryl chloride as a combined CO and Cl source eludes the need for toxic, gaseous carbon monoxide, thus facilitating the synthesis of high-value products from readily available aryl (pseudo)halides. The combination of palladium(0), Xantphos, and an amine base is essential to promote this broadly applicable catalytic reaction. Overall, this reaction provides access to a great variety of carbonyl-containing products through in situ transformation of the generated aroyl chloride. Combined exptl. and computational studies support a reaction mechanism involving in situ generation of CO. And Methyl 3-methylbenzoate (cas: 99-36-5) was used in the research process.

Kasting, B. J.;Beasley, M. S.;Guiseppi-Elie, A.;Richert, R.;Ediger, M. D. published 《Relationship between aged and vapor-deposited organic glasses: Secondary relaxations in methyl-m-toluate》. The research results were published in《Journal of Chemical Physics》 in 2019.Recommanded Product: 99-36-5 The article conveys some information:

In situ interdigitated electrode broadband dielec. spectroscopy was used to characterize the excess wing relaxations in vapor-deposited and aged glasses of methyl-m-toluate (MMT, T_g = 170 K). MMT displays typical excess wing relaxations in dielec. spectra of its supercooled liquid and glasses. Phys. vapor deposition produced glasses with degrees of suppression of the excess wing relaxation that varied systematically with deposition conditions, up to a maximum suppression of more than a factor of 3. The glass deposited at a relatively high temperature, 0.96 T_g (163 K), showed the same amount of suppression as that of a liquid-cooled glass aged to equilibrium at this temperature The suppression of the excess wing relaxation was strongly correlated with the kinetic stability of the vapor-deposited glasses. Comparisons with aged MMT glasses allowed an estimate of the structural relaxation time of the vapor-deposited glasses. The dependence of the estimated structural relaxation times upon the substrate temperature was found to be stronger than Arrhenius but weaker than Vogel-Fulcher-Tammann dependence predicted from extrapolation of relaxation times in the supercooled liquid Addnl., this work provides the first example of the separation of primary and secondary relaxations using phys. vapor deposition.

COA of Formula: C9H10O2In 2019, Zhang, Rong;Yang, Xi;Tao, Zheng;Wang, Xiao;Wang, Huixiang;Wang, Liancheng;Lv, Baoliang published 《Insight into the Effective Aerobic Oxidative Cross-Esterification of Alcohols over Au/Porous Boron Nitride Catalyst》. 《ACS Applied Materials & Interfaces》published the findings. The article contains the following contents:

Boron nitride (BN) has attracted great attention with an unexpected ability in aerobic catalysis. Still, its related probe reactions are relatively rare, and the effect of the BN-supported metal catalyst on O₂ activation is still ambiguous, and opinions are varied. In this work, the porous BN (pBN)-supported Au catalyst with a porous structure and exposed edges exhibits high activity in the oxidative cross-esterification reactions between the aromatic and C₁-C₃ aliphatic alcs. at ambient temperature The turnover frequency value for Me benzoate is 118 h^-1 at 30 °C, and the calculated apparent activation energy (Ea, 58 kJ/mol) is comparable to that of AuPd/TiO₂, Ru/Al₂O₃, and PdBiTe catalysts. Combined with temperature-programmed desorption (TPD) results, the loading of Au enhances the desorption of O₂ and the interaction with alcs.; thus, a synergistic effect between the O-rich pBN and Au is considered. The free-radical scavenger can dramatically suppress the conversion (∼6%), suggesting that the reaction proceeds via the O₂* radicals. According to the vibration of ν_O-O, δ_OO-H, and ν_B-O-O-B detected by attenuated total reflectance-IR spectroscopy (ATR-IR), we are prone to consider the oxygen activation route by the edge B atoms. Then, a possible L-H reaction mechanism was proposed: benzyl alc. and O₂ adsorb on the Au/pBN initially, then O₂ is converted to O₂*, and the α-H elimination proceeds; as the semi-acetal formed, another α-H elimination proceeds and Me benzoate is finally formed. The experimental procedure involved many compounds, such as Methyl 3-methylbenzoate (cas: 99-36-5) .

The article contains the following contents:

Common bed bug Cimex lectularius (L.) (Hemiptera: Cimicidae) infestations are on the rise and due to the development of pesticide resistance they are becoming more difficult to control, affordably. We evaluated a naturally occurring compound Me benzoate (MB) and related analogs, previously reported to have insecticidal activity on several agricultural pests, for its fumigant action on the common bed bug, C. lectularius L. A discriminating concentration was used to determine the effectiveness of MB, and several of its analogs as fumigants in a laboratory assay. It was found that MB provided >90% control of adult bed bugs in this laboratory fumigant assay. The LC₅₀ values were calculated for MB against both a pyrethroid-susceptible and a pyrethroidresistant strain of common bed bugs. It was determined that both strains were susceptible in this laboratory assay. However, when MB was tested in a field-like assay and compared to a com. available bed bug control product, it was found to be significantly less effective compared to the com. product. Our study has found that while MB has the potential to be used as a bed bug control agent, refinements in the delivery system will be needed to increase efficacy under field-like conditions.Methyl 3-methylbenzoate (cas: 99-36-5) were involved in the experimental procedure.

COA of Formula: C9H10O2《Umpolung α-Silylation of Cyclopropyl Acetates via Low-Temperature Catalytic C-C Activation》 was published in 2019. The authors were Avullala, Thirupataiah;Asgari, Parham;Hua, Yuanda;Bokka, Apparao;Ridlen, Shawn G.;Yum, Kyungsuk;Dias, H. V. Rasika;Jeon, Junha, and the article was included in《ACS Catalysis》. The author mentioned the following in the article:

The authors report a redox-neutral, catalytic C-C activation of cyclopropyl acetates to produce Si-containing five-membered heterocycles in a highly regio- and chemoselective fashion. The umpolung α-selective silylation leading to dioxasilolanes is opposed to contemporary β-selective C-C functionalization protocols of cyclopropanols. Lewis base activation of dioxasilolanes as α-silyl carbinol equivalent undergoes the unconventional [1,2]-Brook rearrangement to form tertiary alcs. Notably, mechanistic studies indicate that an electrophilic metal-π interaction harnessing highly fluorinated Tp(CF₃)₂Rh(nbd) catalyst permitted a low temperature C-C activation. To complete the study, the researchers used Methyl 3-methylbenzoate (cas: 99-36-5) .

Feng, Yan;Chen, Jian;Zhang, Aijun published 《Commercially Available Natural Benzyl Esters and Their Synthetic Analogs Exhibit Different Toxicities against Insect Pests》 in 2018. The article was appeared in 《Scientific Reports》. They have made some progress in their research.Application In Synthesis of Methyl 3-methylbenzoate The article mentions the following:

Benzyl Me ester, also known as Me benzoate (MB), is a volatile organic compound that exists naturally as a floral fragrance in many plants. Our behavioral bioassays show that MB and some of its naturally occurring and synthetic analogs kill insects at different life stages. Compared to com. pesticides containing pyriproxyfen and acetamiprid, MB and some analogs are 1.3 to 3.4 times more toxic to gypsy moth larvae and brown marmorated stinkbug nymphs. The arthropod repellent DEET is also a benzyl ester, and shares the same chem. skeleton with MB. They differ by the diethylamide ester and a Me group on the benzene ring in DEET. However, unlike MB, DEET does not kill insects; instead, it deters or repels them. Exactly how DEET causes the repellent effect in target organisms is still a mystery. Due to the MB’s structural similarity to DEET, exploring the structure – activity relationship (SAR) of the MB analogs will provide useful information for the discovery of the mode and mechanistic actions of DEET as an insect repellent. In addition, the SAR will allow researchers to modify the chem. structure of the MB mol., leading to the development of more efficient, safe, and environmentally – friendly green pesticides. The experimental procedure involved many compounds, such as Methyl 3-methylbenzoate (cas: 99-36-5) .

Herein, simple acyl sources, viz. Me and Ph esters, which acylate oxindoles via the mixed Claisen condensation are reported. This straightforward protocol is mediated by LiHMDS and KO^tBu and successfully applied to a wide range of substrates. It is a noteworthy transformation that skips the stepwise generation of enolates and acylation, and the reaction is performed at a moderate temperature with no side reactions. This protocol produces the first examples of ortho-substituents in an aryl ring flanked with electron-donating and electron-withdrawing substrates.

The article was appeared in 《Journal of Organic Chemistry》. They have made some progress in their research.Reference of Methyl 3-methylbenzoate The article mentions the following:

Chemoselective deprotonative functionalization of benzylic C-H bonds is challenging, because the arene ring contains multiple aromatic C(sp²)-H bonds, which can be competitively deprotonated and lead to selectivity issues. Recently it was found that bimetallic [MN(SiMe₃)₂ M = Li, Na]/Cs⁺ combinations exhibit excellent benzylic selectivity. Herein, is reported the first deprotonative addition of toluenes to Weinreb amides mediated by LiN(SiMe₃)₂/CsF for the synthesis of a diverse array of 2-arylacetophenones. Surprisingly, simple Me benzoates also react with toluenes under similar conditions to form 2-arylacetophenones without double addition to give tertiary alc. products. This finding greatly increases the practicality and impact of this chem. Some challenging substrates with respect to benzylic deprotonations, such as fluoro and methoxy substituted toluenes, are selectively transformed to 2-aryl acetophenones. The value of benzylic deprotonation of 3-fluorotoluene is demonstrated by the synthesis of a key intermediate in the preparation of Polmacoxib.Methyl 3-methylbenzoate (cas: 99-36-5) were involved in the experimental procedure.
