Phenethylboronic acid Usage And Synthesis

Chemical Properties

off-white powder

Uses

Phenethylboronic acid is a good inhibitor of chymotrypsin.

Uses

2-Phenylethylboronic acid is used as a reactant in Suzuki-Miyaura cross-coupling reactions, reactions with α-diazocarbonyl compounds, C-H functionalization of quinones, cross-coupling with aromatic amines and arylation & alkylation of diphenylisoxazole. It has been also used as reactant in studies of the stability of boronic esters to hydrolysis.
