Pyridine ligands as promoters in Pd(II/0)-catalyzed C-H olefination reactions.

Asako Kubota1, Marion H Emmert, Melanie S Sanford.   

Abstract

Commercially available pyridine ligands can significantly enhance the rate, yield, substrate scope, and site selectivity of arene C-H olefination (Fujiwara-Moritani) reactions. The use of a 1:1 ratio of Pd/pyridine proved critical to maximize reaction rates and yields.
