Symmetrical and unsymmetrical 2,6-dialkyl-1,1′-biaryls by combined catalysis of aromatic alkylation via palladacycles and Suzuki-type coupling
Abstract
The title compounds are made readily accessible by a catalytic procedure, occurring under mild conditions, based on palladium-mediated ortho alkylation of aromatic iodides with alkyl bromides followed by reaction with arylboronic acids.
