Abstract

Abstract Catalytic activities of NHC-derived nickel–pincer complexes for the Suzuki–Miyaura coupling reactions of aryl/alkenyl tosylates and mesylates are described. In the presence of a catalytic amount of nickelacycle 1a, a wide array of tosylates and mesylates reacted with several aryl-and alkenylboronic acids to afford the coupling products, generally in high yields. Fine tuning of the reaction conditions for each class of electrophiles was achieved ...
