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., Category: alcohols-buliding-blocks

In general, the hydroxyl group makes alcohols polar. 72824-04-5, formula is C9H17BO2, Because of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. Category: alcohols-buliding-blocks

Ren, Xiaoxiao;Gao, Xing;Min, Qiao-Qiao;Zhang, Shu;Zhang, Xingang research published 《 (Fluoro)alkylation of alkenes promoted by photolysis of alkylzirconocenes》, the research content is summarized as follows. An unprecedented example of alkylzirconocenes Cp2ZrCl(CH2)2R (R = Bn, dimethyl(phenyl)silyl, trimethylsilyl, etc.) promoted difluoroalkylation of alkyl- and silyl-alkenes RCH=CH2 with a variety of unactivated difluoroalkyl iodides and bromides R1C(F2)X (R1 = [(ethanesulfonyl)oxy]methyl, (morpholin-4-yl)carbonyl, 3-[(4-chlorophenyl)carbonyloxy]propyl, etc.; X = I, Br) under the irradiation of visible light without a catalyst. The resulting difluoroalkylated compounds RC(F2)R1 can serve as versatile synthons in organic synthesis. The reaction can also be applied to activated difluoroalkyl, trifluoromethyl, perfluoroalkyl, monofluoroalkyl, and nonfluorinated alkyl halides, providing a general method to controllably access fluorinated compounds Preliminary mechanistic studies reveal that a single electron transfer (SET) pathway induced by a Zr(III) species is involved in the reaction, in which the Zr(III) species is generated by the photolysis of alkylzirconocene with blue light.
