一般描述

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

应用

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.[3] It was used to investigate the effect on oligomerization of increased steric bulk in dimethylindium(III) chalcogenolates.[4] It may be used to form α,α-dimethyl-β-phenyl hydrostyrene by reacting with phenylboronic acid.[2]

The effect on oligomerization of increased steric bulk in dimethylindium(III) chalcogenolates (Me(2)InER') (E = O, S, Se) has been examined. The facile reaction of Me(3)In with a series of phenols, thiophenols and selenophenols afforded the compounds [Me(2)InO(C(6)H(5))](2) (1), [Me(2)InO(2,6-Me(2)C(6)H(3))](2) (2)
