Abstract
This review provides a summary of research progress of non-phosgene synthesis of N-substituted carbamates using various carbonyl reagents,such as CO,dimethyl carbonate,CO2 and alkyl carbamates. The advantages and disadvantages of various synthetic methods are analyzed. Low toxicity,high activity and simple preparation make alkyl carbamates the most industrialized carbonyl reagent for N-substituted carabamates synthesis and the N-substituted carbamates synthesized from CO2is a research focus on green chemistry,which provides a new route for chemical utilization of CO2.
