Abstract

Abstract: Catalytic systems combining ortho-(dimesitylboryl) phenylphosphines and palladium precursors have been evaluated in the Suzuki–Miyaura couplings of chloro-N- heterocycles, in particular 2-chloroACHTUNGTRENNUNGpyridines, with arylboronic acids. The Lewis basic character of the substrates does not interfere with the Lewis acidic site of the ligands, even for a substrate featuring free NH2 groups. The influence of several ...
