One-pot stibine modified Co2(CO)8 catalyzed reductive N-alkylation of primary amides with carbonyl compounds
摘要:
A one-pot stibine modified Co-2(CO)(8) homogeneous catalytic reductive N-alkylation of primary amides using aldehydes/ketones as alkylating agents, is reported. Good to excellent yields of a wide range of secondary amides are obtained (up to 97%) under relative mild conditions. (C) 2012 Elsevier Ltd. All rights reserved.

direct synthesis of anilides and N-benzylamides under mild conditions (room temperature, ambient pressure) in the absence of metal catalyst and external oxidizing agents using nitriles RCN (R=Me, Et) as amide source is described. This electrochemical approach features moderate to high yields, a broad scope of arenes with different functional groups and is amenable to gram scale synthesis. The key role of
