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., Formula: C9H17BO2

In general, the hydroxyl group makes alcohols polar. Those groups can form hydrogen bonds to one another and to most other compounds. 72824-04-5, formula is C9H17BO2, Owing to the presence of the polar OH alcohols are more water-soluble than simple hydrocarbons. Methanol, ethanol, and propanol are miscible in water. Butanol, with a four-carbon chain, is moderately soluble. Formula: C9H17BO2

Kanazawa, Tomoaki;Nishikawa, Tsuyoshi;Ouchi, Makoto research published 《 Orthogonal C-B Bond Transformation as an Approach for Versatile Synthesis of End-Functionalized Polymers》, the research content is summarized as follows. Conventionally inaccessible end-functionalized vinyl polymers were synthesized via orthogonal side-chain replacement for terminal and repeating units of poly(alkenyl boronate)s. A terminal-defined polymer of isopropenyl boronic acid pinacol ester (IPBpin) was synthesized via RAFT polymerization, and subsequent cobalt (Co)-catalyzed end olefination afforded the polymer carrying the C(sp2)-B bond at the terminal and the C(sp3)-B bond in repeating units. Herein, the terminal C(sp2)-B bond was selectively transformable via palladium (Pd)-catalyzed Suzuki-Miyaura cross coupling, and subsequent transformation of the repeating C(sp3)-B unit gave the poly(α-Me vinyl alc.) [poly(MVA)] bearing various functional groups at the terminal. The boron-based stepwise polymer reaction thus overcame the synthetic difficulty of the end-functionalized poly(MVA), which is ascribed to the poor polymerization ability of the corresponding acetate monomer, i.e., isopropenyl acetate.
