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. , Product Details of C9H17BO2
Tanaka, Tsukushi;Yazaki, Ryo;Ohshima, Takashi research published 《 Chemoselective Catalytic α-Oxidation of Carboxylic Acids: Iron/Alkali Metal Cooperative Redox Active Catalysis》, the research content is summarized as follows. Chemoselective catalytic activation of carboxylic acid for a 1e– radical process is described. The α-oxidation of a variety of carboxylic acids HOC(O)CH2R (R = 4-methylphenyl, 2H-1,3-benzodioxol-5-yl, thiophen-3-yl, etc.), which preferentially undergo undesired decarboxylation under radical conditions, proceeded efficiently under the optimized conditions. Chemoselective enolization of carboxylic acid was also achieved even in the presence of more acidic carbonyls. Extensive mechanistic studies revealed that the cooperative actions of iron species and alkali metal ions derived from 4 Å mol. sieves substantially facilitated the enolization. For the first time, catalytic enolization of unprotected carboxylic acid was achieved without external addition of stoichiometric amounts of Bronsted base. The formed redox-active heterobimetallic enediolate efficiently coupled with free radical TEMPO, providing synthetically useful α-hydroxy and keto acid derivatives R3OC(O)CH(OR2)R (R2 = 2,2,6,6-tetramethylpiperidin-1-yl, 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-yl, 2,2,6,6-tetramethyl-4-(prop-2-yn-1-yloxy)piperidin-1-yl, 2,2,6,6-tetramethyl-4-(methylcarbonylamino)piperidin-1-yl; R3 = H, Me).
Product Details of C9H17BO2, 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.
