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 CO2 is a research focus on green chemistry，which provides a new route for chemical utilization of CO2.

Key words: non-phosgene, N-substituted carabamates, carbonyl reagents, carbon dioxide, synthesis, catalysis

摘要： 简述了近年来国内外非光气合成N-取代氨基甲酸酯的主要方法，重点阐述了以CO、碳酸二甲酯、CO2、氨基甲酸烷基酯等为羰基化试剂的合成途径，并对各合成方法的优缺点进行了系统的评述。指出氨基甲酸烷基酯以其毒性低、活性高以及制备简单等优点使其成为合成N-取代氨基甲酸酯最具工业化应用前景的羰基化试剂；而以CO2为羰基化试剂合成N-取代氨基甲酸酯的路线符合当前绿色化学的主题，为CO2的资源化利用提供了新途径，是今后的研究热点。
