N-formylation of amines using phenylsilane and CO2 over ZnO catalyst under mild condition

Several research studies have been conducted on N -formylation of amines using phenylsilane and CO 2 . However, most of these studies involved tedious processes of catalyst preparation or complex procedures. In the present study, we describe the use of a simple and commercially available ZnO catalyst for selective N -formylation of amines under mild condition. High-yielding N -formylation products with good recyclability and wide substrate scope were obtained, which can promote fine chemical synthesis and CO 2 capture.
