Abstract

Isomeric carborane-containing phosphite ligands possessing different electronic properties have been synthesized. Their use in the Pd-catalyzed Suzuki-Miyaura reaction involving activated aryl bromides showed that phosphite with 9-o-carborane substituent has proved more efficient, with carboranyl phosphite having 1-m- carborane fragment being more efficient in the reactions with nonactivated aryl bromides.
