General description

1-Bromo-2,4,6-tri-tert-butylbenzene (2,4,6-tri-tert-butylbromobenzene) is a hindered aryl bromide. 1-Bromo-2,4,6-tri-tert-butylbenzene on reaction with phenylboronic acid yields α,α-dimethyl-β-phenyl hydrostyrene.

Application

1-Bromo-2,4,6-tri-tert-butylbenzene was used in the synthesis of bulky biarylphosphine ligand. This ligand was reported to participate in the Pd-catalyzed C-O cross-coupling of a wide range of aryl halides and phenols under milder conditions. It was used to investigate the effect on oligomerization of increased steric bulk in dimethylindium(III) chalcogenolates. It may be used to form α,α-dimethyl-β-phenyl hydrostyrene by reacting with phenylboronic acid.
