چکیده
|
Summary: simple and highly efficient procedure for n-formylation of various amines was carried out in the presence of the immobilized sufuric acid on activated charcoal as an efficient promoter system. all reactions were taken place in refluxing ethyl formate (54 °c) under mild reaction conditions. the product formamides were obtained in high to excellent yields (83-95%) within 4-80 min.
