In 2022,Huang, Lele; Liu, Xu-Feng; Zou, Jinglin; Duan, Xinping; Chen, Zuo-Chang; Zhou, Zhe-Hui; Ye, Linmin; Liang, Xuelian; Xie, Su-Yuan; Yuan, Youzhu published an article in Journal of Catalysis. The title of the article was 《Atomic ruthenium stabilized on vacancy-rich boron nitride for selective hydrogenation of esters》.Application In Synthesis of Methyl 3-hydroxypropanoate The author mentioned the following in the article:
Constructing and taming metal-support interaction of atoms and/or clusters has emerged as a promising protocol to maximize the catalytic performance of noble metal-based materials. Here, we report at. ruthenium (Ru) with the oxidized state immobilized on defect-rich hexagonal boron nitride (d-BN) nanosheets and the essential interfacial electronic effect on Ru deduced from B- and N-vacancies for superior selective hydrogenation of esters. Exptl. results indicate that strong electronic interplay exists between vacancies and at. Ru species. Unlike defect-free com. hexagonal BN (h-BN), d-BN can highly stabilize the active Ru species in at. scale with oxidation state, and the obtained Ru/d-BN significantly increases the catalytic activity and durability. Specifically, the turnover frequency of Ru/d-BN is more than one order of magnitude higher than that of the conventional optimized Ag/SiO2 catalyst for the selective hydrogenation of di-Me oxalate to Me glycol. Systematic characterizations show that the Ru on B- and N-vacancies, and the defective BN serves as electron acceptor. The findings demonstrate the overall electronic effect on the electron-rich feature of Ru on d-BN, such that the electronic metal-support interactions cause the Ru species to favor the adsorption and selective scission of C-O bonds in esters, revealing a highly efficient hydrogenation catalysis. The experimental part of the paper was very detailed, including the reaction process of Methyl 3-hydroxypropanoate(cas: 6149-41-3Application In Synthesis of Methyl 3-hydroxypropanoate)
Methyl 3-hydroxypropanoate(cas: 6149-41-3) belongs to esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
