Cu-ACP-Am-Fe3O4@SiO2: an efficient and recyclable heterogeneous catalyst for the Chan-Lam coupling reaction of boronic acids and amines

摘要

We have developed an efficient method for Cu-ACP-Am-Fe3O4@SiO2 catalyzed Chan-Lam coupling of phenylboronic acid with primary amine furnished secondary amines. The catalyst offered virtues like mild reaction conditions, magnetically separable, and reusable and exhibits excellent performance in terms of good product yield and high turnover number.
