PHOSGENE-FREE PROCESS FOR PREPARING CARBAMATES |
摘要 |
A phosgene-free method for preparing a carbamate from a compound containing an amine group involves reacting the compound with an alkylating agent in the presence of carbon dioxide and cesium carbonate. A reaction can take place under standard pressure and temperature conditions and produces carbamates in a high yield with low by-product formation. |
