Abstract: Formamide is an important intermediate for the preparation of drugs, dyes, perfumes and other functional chemicals and synthetic reagents, and the development of simple, green and economic strategy for the synthesis of formamides has always attracted extensive attention in the field of synthetic chemistry and industry. In this paper, a copper acetate catalyzed strategy for the formation of formamides through one-pot direct reduction and N-formylation of nitroarenes in a formic acid-ammonium acetate buffer system has been developed. This approach provides a simple and inexpensive strategy access to various formamides with up to 91% yields under optimal conditions. The yield of the product is 77% and there is no loss of the catalyst activity when it is recycled for five times.

Key words: Formamide, N-formylation, Nitroarene, Cu(II)-catalyzed, Formic acid-ammonium acetate buffer system
