Abstract
The present invention relates to a method for preparing primary amides from tertiary or secondary amides substituted with various alkyl groups through a transamidation reaction without a metal catalyst in room-temperature conditions by adding ammonium carbonate ((NH)CO), wherein the method is eco-friendly since various secondary and tertiary amides that are not toxic or corrosive are used as starting materials and ammonium carbonate ((NH)CO) that is neither a strong acid nor a strong base is used, and the method is economical since various primary amides can be synthesized with an excellent yield at room temperature without a metal catalyst.
