Isocyanates are useful building blocks for the synthesis of amides, although their widespread use has been limited by their high reactivity, which often results in poor functional group tolerance and a propensity to oligomerize. Herein, a rhodium-catalyzed synthesis of amides is described coupling boroxines with blocked (masked) isocyanates. The success of the reaction hinges on the ability to form both the isocyanate and the organorhodium intermediates in situ. Relying on masked isocyanate precursors and on the high reactivity of the organorhodium intermediate results in broad functional group tolerance, including protic nucleophilic groups such as amines, anilines, and alcohols.

The aim of this work was to undertake a detailed analysis on chemical constituents of brown propolis, originating from four different states (Bahia, Minas Gerais, Parana and Sergipe) of Brazil. The volatile profile was determined by using HS-SPME-GC-MS along with the determination of total phenolic compounds content, flavonoids and antioxidant activity. A total of 315 volatile compounds were identified, however, several of them have not been reported so far in the Brazilian brown propolis. The terpenes represented the major class with 40.92-84.66% of the total area in the chromatograms. PCA analysis of the majority of compounds successfully indicated the volatile profile of each propolis sample according to their geographical origin. The analysis of volatile compounds and its characterization also varied significantly and confirmed that these depended on the geographical area of collection of propolis. The data generated in this work may help in establishing criteria for quality control and tracking the specific region of propolis production in different states of Brazil.

Conventional methods to improve the flame retardancy of polymeric materials usually involve the use of flame-retardant elements such as Cl, Br and P, however, their use may bring more smoke and toxic gases hazards, and more importantly, cause non-negligible environmental and ecological problems. In this work, we put forward a novel green strategy that eliminates the use of any conventional flame-retardant elements to improve the flame retardancy by incorporating a synergistically cross-linkable structure (named PN) containing phenylacetylene and phenylimide groups. The resulting PN copolymer exhibited an excellent 55% lower smoke release rate and 68% lower heat release rate than the pure polymer, as well as a high LOI value of 32% and UL-94 V-0 rating with excellent anti-dripping performance. TG-DSC, rheological and FTIR results proved the high cross-linking ability of the PN copolymer due to the synergistic cross-linking effect between the imide-isoimide rearrangement of phenylimide and the self-cross-linking of phenylacetylene. The SEM, Raman and Py-GC/MS results further upheld the condensed phase flame-retardant mechanism. This eco-friendly synergistic cross-linking strategy provided new perspective for the design and synthesis of polymeric materials with excellent flame retardancy, great anti-dripping performance, and low release of heat, smoke, and toxic gas.

In the presented work, five bio-based and bio-degradable cyclic esters, i.e. lactones, have been investigated as possible phase change materials for applications in latent heat storage systems. Commercial natural lactones such as epsilon-caprolactone and gamma-valerolactone were easily purchased through chemical suppliers, while 1,2-campholide, oxa-adamantanone and dibenzochromen-6-one were synthesized through Baeyer-Villiger oxidation. The compounds were characterized with respect to attenuated total reflectance spectroscopy and gas chromatography coupled with mass spectroscopy, in order to confirm their chemical structures and identity. Subsequently, thermogravimetric analysis and differential scanning calorimetry were used to measure the phase change temperatures, enthalpies of fusion, degradation temperatures, as well to estimate the degree of supercooling. The lactones showed a wide range of phase change temperatures from -40 degrees C to 290 degrees C, making them a high interest for both low and high temperature latent heat storage applications, given the lack of organic phase change materials covering phase change temperature ranges below 0 degrees C and above 80 degrees C. However, low enthalpies of fusion, high degrees of supercooling and thermal degradations at low temperatures were registered for all samples, rendering them unsuitable as phase change materials.

Nanosized structural defects in metal-organic frameworks (MOFs) attract growing attention and often remarkably enhance functional properties of these materials for various applications. In this work, a series of MOFs [Cu-2(TPTA)(1-x)(BDPBTR)(x)] (H(4)TPTA, [1,1′:3′,1 ”-terphenyl]-3,3 ”,5,5 ”-tetracarboxylic acid; H4BDPBTR, 1,3-bis(3,5,dicarboxyphenyl)-1,2,4-benzotriazin-4-yl radical)) with a new stable radical linker doped into the structure has been synthesized and investigated using Electron Paramagnetic Resonance (EPR). Mixed linkers H(4)TPTA and H4BDPBTR were used to bridge copper(II) paddle-wheel units into a porous framework, where H4BDPBTR is the close structural analogue of H(4)TPTA. MOFs with various x = 0-0.4 were investigated. EPR studies indicated that the radical linker binds to the copper(II) units differently compared to diamagnetic linker, resulting in the formation of nanosized structural defects. Moreover, remarkable kinetic phenomena were observed upon cooling of this MOF, where slow structural rearrangements and concomitant changes of magnetic interactions were induced. Thus, our findings demonstrate that doping of structurally mimicking radical linkers into MOFs represents an efficient approach for designing target nanosized defects and introducing new magnetostructural functionalities for a variety of applications.

A family of four novel pyrazinyl-hydrazone based ligands have been synthesized with differing functionality at the 5-position of the central aromatic ring. Previous work has shown such ligands to form dinuclear triple mesocates which pack to form hexagonal channels capable of gas sorption. The effect of the peripheral functionality of the ligand on the crystal packing was investigated by synthesizing complexes1to4which feature amino, bromo, iodo and methoxy substituents respectively. Complexes1to3crystallized in the same hexagonal space groupP6(3)/mand featured 1D channels. However, on closer inspection while the packing of1is mediated by hydrogen bonding interactions, the packing of complexes2and3are not, due to a subtlety different pi-pi stacking interaction enforced by the halogen substituent. The more bulky nature of the methoxy substituent of4results in the complex crystallizing in the triclinic space groupP-1, featuring an entirely different crystal packing.

A new heterogeneous cobalt catalyst has been synthesized by immobilizing Co species onto a nitrogen-rich porous organic polymer (Co@imine-POP). The heterogeneous catalyst synthesized was efficient in Heck and Sonogashira cross-coupling reactions in green media under mild reaction conditions without inert air and phase transfer agents. This phosphine-, copper-, and palladium-free catalyst was stable under the reaction conditions and could be reused for at least eight successive runs without a discernible decrease in its catalytic activity.

BACKGROUND Environmental safety of the agricultural utilization of livestock and poultry manures from intensive farming is attracting great attention and is effective as a good source of nitrogen for sustainable crop production. The present study aimed to determine the effects of organic poultry manure applications on the biological value and essential oil content of sweet basil (Ocimum basilicum L.). In this context, different doses of chicken, kibele (fermented chicken manure) and turkey manure (750, 1000, 1250 and 1500 kg da(-1)) with a control (no manure) were applied by sowing. RESULTS The essential oils consisted of p-Allyl-anisole as the most abundant component (5.65-17.90%), followed by nerol (6.69-16.11%), linalool (5.10-10.81%) and z-citral (5.23-10.73%). The contents of most of the chemical constituents varied significantly (P < 0.05) with organic poultry manure applications. The highest concentration for essential oils components was found in the chicken manure application. Both the antioxidant activity and total phenolic amounts of the basil extracts varied significantly as the organic poultry manure applications changed. The highest antioxidant activity and total phenolic amounts were obtained in the treatments with chicken manure doses of 1000 and 1250 kg da(-1), which were significantly different compared to the other treatments and the control treatment. Evaluation of antimicrobial activity of the essential oils against bacterial strains: Escherichia coli ATCC 35218, Staphylococcus aureus ATCC 43300 and Candida albicans ATCC 10231 was assessed by the disc diffusion method and determination of the minimum inhibitory concentration. The results of antimicrobial assays indicated that all of the tested microorganisms were affected. The highest antibacterial activity against all tested microbial species was observed with 1250 kg da(-1) chicken manure applications. CONCLUSION Among the organic poultry fertilizations, chicken fertilization was of particular interest. Especially, chicken manure doses of 1000-1250 kg da(-1) had the highest antibacterial and antioxidant activity, as well as total phenolics, flavonoids and essential oil components.

A conceptionally novel nucleophilic substitution approach to synthetically important alkyl bromides is presented. Using molecular bromine (Br-2), readily available secondary benzyl and tertiary alkyl phenyl sulphides are converted into the corresponding bromides under exceptionally mild, acid- and base-free reaction conditions. This simple transformation allows the isolation of elimination sensitive benzylic beta-bromo carbonyl and nitrile compounds in mostly high yields and purities. Remarkably, protic functionalities such as acids and alcohols are tolerated. Enantioenriched benzylic beta-sulphido esters, readily prepared by asymmetric sulpha-Michael addition, produce the corresponding inverted bromides with high stereoselectivities, approaching complete enantiospecificity at -40 degrees C. Significantly, the reported benzylic beta-bromo esters can be stored without racemisation for prolonged periods at -20 degrees C. Their synthetic potential was demonstrated by the one-pot preparation of gamma-azido alcohol (S)-5 in 90% ee. NMR studies revealed an initial formation of a sulphide bromine adduct, which in turn is in equilibrium with a postulated dibromosulphurane intermediate that undergoes C-Br bond formation.
