Safety of 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, 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.

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. , Safety of 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane

Li, Yangyang;Wei, Hong;Wu, Dong;Li, Zheqi;Wang, Wang;Yin, Guoyin research published 《 Nickel-Catalyzed Chemodivergent 1,1-Difunctionalization of Unactivated α-Olefins with Alkynyl Electrophiles and B2pin2》, the research content is summarized as follows. A nickel-catalyzed, chemodivergent 1,1-alkynylboration, and 1,1-dialkynylation of unactivated α-olefins was reported. This study not only provided an efficient and modular protocol for the divergent synthesis of propargylic boronic esters, their corresponding alcs., and gem-dialkynylalkanes I [R = TIPS, C(Me)2OTBS, C(4-ClC6H4)2OTBS, etc.; R1 = OH, CCTIPS; R2 = Me, n-hexyl, Ph(CH2)2, etc.] but also achieved a controllable, single or double cross-coupling of Ni/B bimetallic intermediates. Mechanistic studies revealed that diboron reagent (B2pin2) plays a significant role in dialkynylation reaction, serving as both the reductant and transient assisting group. Notably, both reactions showed high regioselectivities and good functional group tolerance. In addition, the synthetic value of products was demonstrated with several downstream transformations.
