Abstract

The activity of the complex (IPr) PdCl (η2-N, C-C12H7NMe2), 1 [IPr=(N, N'-bis (2, 6- diisopropylphenyl) imidazol)-2-ylidene], in the Suzuki-Miyaura cross-coupling reaction involving unactivated aryl chlorides and triflates with arylboronic acids at room temperature in technical grade 2-propanol is described. These conditions allow for the synthesis of di- and tri-ortho-substituted biaryls in very short reaction times. This complex also displays ...
