ZnO as a New Catalyst for N-Formylation of Amines under Solvent-Free Conditions
摘要:
The treatment of amines with formic acid in the presence of ZnO under solvent-free conditions brings about highly and efficient N-formylation to give the corresponding formamides in excellent yields. The N-formylation reaction not only involves mild conditions, simple operation, and high yields but also high chemoselectivity.
