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. Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
Li, Kuiliang;Sun, Xiang;Zhao, Shuangshuang;Li, Tong;Zha, Zhenggen;Wang, Zhiyong research published 《 Zn-Catalyzed enantioselective allylation and allenylation of isatins by virtue of a proline-derived chiral ligand》, the research content is summarized as follows. An asym. allylation and allenylation of isatins with facile organoboron reagents was developed under the catalysis of a Lewis acid. A series of optically pure 3-allyl-3-hydroxyoxindoles I [R1 = H, Me, Ph, etc.; R2 = H, 5-Me, 4-Br, etc.; R3 = CH2CH=CH2, CH(Me)CH=CH2, CH2C(Me)=CH2] and 3-allenyl-3-hydroxyoxindoles I [R3 = CH=C=CH2] could be obtained in excellent yields (up to 99% yield) and high enantioselectivities (up to 97% ee). The possible transition state was supported by DFT calculation and the corresponding mechanism was proposed. A gram scale experiment and further functionalization of these chiral 3-hydroxyoxindoles were established.
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., Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
