An efficient N-arylation of heterocycles with aryl-, heteroaryl-, and vinylboronic acids catalyzed by copper fluorapatite

Kantam, Mannepalli Lakshmi,Venkanna, Gopaladasu Tirupati,Kumar, Kota Balaji Shiva,Subrahmanyam, Vura Bala

, p. 974 - 979 (2010)

N-Arylation of N-containing heterocycles, such as pyrazoles, imidazoles, and benzimidazoles with aryl-, heteroaryl-, and vinylboronic acids was efficiently carried out by copper fluorapatite (CuFAP) catalyst in MeOH at room temperature under base-free conditions. The N-arylated heterocycles were isolated in good-to-excellent yields.
