4-Biphenylboronic acid Usage And Synthesis

Chemical Properties

Solid

Uses

suzuki reaction: Suzuki coupling of 2-(4-bromophenyl)thiophene with phenylboronic acid and 4-biphenylboronic acid are used for the preparation of 4-(2-thieny)biphenyl and 4-(2-thienyl)-1,1':4,1''-biphenyl respectively. Coupling of two equivalents of 4-(2-thienyl)phenylboronic acid with 1,4-diiodobenzene gives 4,4''-bis(2-thienyl)-1,1':4,1''-terphenyl and with 2,5-diiodothiophene, 2,5-bis[4-(2-thienyl)-phenyl]-thiophene is obtained.

Uses

Used in Suzuki reactions and as intermediates of liquid crystals.
