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
Goswami, Prithwish;Cho, Sung Yeon;Park, Jin Hyun;Kim, Woo Hee;Kim, Hyun Jin;Shin, Myoung Hyeon;Bae, Han Yong research published 《 Efficient access to general α-tertiary amines via water-accelerated organocatalytic multicomponent allylation》, the research content is summarized as follows. A tetrasubstituted carbon atom connected by three sp3 or sp2-carbons with single nitrogen, i.e., the α-tertiary amines I [R = n-Pr, CH2CO2Et, Ph, etc.; R1 = Me, Et, n-Pr, etc.], was an essential structure of diverse naturally occurring alkaloids and pharmaceuticals. The synthetic approach toward ATA structures was intricate, therefore, a straightforward catalytic method had remained a substantial challenge. Herein, an efficient water-accelerated organocatalytic allylation to directly access ATA incorporating homoallylic amine structures I by exploiting readily accessible general ketones/keto esters as useful starting material along with allyl boronic acid esters and benzhydrazide/amines. The synergistic action of a hydrophobic Bronsted acid in combination with a squaramide hydrogen-bonding donor under aqueous condition enabled the facile formation of the desired moiety I. The developed exceptionally mild but powerful system facilitated a broad substrate scope and enabled efficient multi-gram scalability.
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
