Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 72824-04-5, formula is C9H17BO2, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Electric Literature of 72824-04-5
Miura, Hiroki;Hachiya, Yuka;Nishio, Hidenori;Fukuta, Yohei;Toyomasu, Tomoya;Kobayashi, Kosa;Masaki, Yosuke;Shishido, Tetsuya research published 《 Practical Synthesis of Allyl, Allenyl, and Benzyl Boronates through SN1′-Type Borylation under Heterogeneous Gold Catalysis》, the research content is summarized as follows. Efficient borylation of sp3 C-O bonds by supported Au catalysts is described. Au nanoparticles supported on TiO2 showed high activity under mild conditions employing low catalyst loading conditions without the aid of any additives, such as phosphine and bases. A variety of allyl, propargyl, and benzyl substrates participated in the heterogeneously catalyzed reactions to furnish the corresponding allyl, allenyl, and benzyl boronates in high yields. Besides, Au/TiO2 was also effective for the direct borylation of allylic and benzylic alcs. A mechanistic investigation based on a Hammett study and control experiments revealed that sp3 C-O bond borylation over supported Au catalysts proceeded through SN1′-type mechanism involving the formation of a carbocationic intermediate. The high activity, reusability, and environmental compatibility of the supported Au catalysts as well as the scalability of the reaction system enable the practical synthesis of valuable organoboron compounds
Electric Literature of 72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.
