摘要

Palladium-catalyzed Suzuki–Miyaura cross-coupling reactions of tetrabutylammonium 2- pyridyltriolborate salts with various aryl (heteroaryl) chlorides can produce the corresponding desired coupling products with good to excellent yields. These tetrabutylammonium salts are more reactive than the corresponding lithium salts. The coupling reactions with aryl chlorides progressed in the presence of PdCl2dcpp (3 mol%) ...
