Abstract

Ruthenium (III) complex,[RuCl (C3S5)(H2O)(PPh3) 2] is an effective catalyst for the homocoupling of the aryl-Grignard reagents (ArMgX) to form biaryl derivatives. The catalytic methodology involves an in situ generation of the Grignard reagents. The method is simpler, economical and of great synthetic utility. The reaction will be environmental friendly due to the involvement of molecular oxygen as oxidant.
