Abstract

trans-PdBr (N-Succ)(PPh3) 2 (1) is a universally effective precatalyst for Suzuki-Miyaura cross-couplings of benzylic halides with aryl-or heteroarylboronic acids. Substituted aryl halides and halogenated cyclic enones can be cross-coupled with aryl-or vinylboronic acids in excellent yields. Catalyst recycling is also demonstrated.
