Chemoselective Chan-Lam Coupling Reactions between Benzimidazoline-2-thiones and Arylboronic Acids
Liu, Xing,Dong, Zhi-Bing
, p. 11524 - 11532 (2019/10/02)
An efficient Chan-Lam-type methodology for the selective synthesis of S-arylbenzimidazoles and N,S-diarylbenzimidazoles was developed. The selectivity was controlled by varying the amount of the catalyst Cu(OAc)2·H2O, temperature, an
