摘要：

Alkyl carbamates are prepared in good yields by oxidative carbonylation of alkylamines using a transition-metal catalyst and sodium iodide promoter. Various homogeneous and heterogeneous transition-metal catalysts are studied. Synthesis of methyl N-methylcarbamate (MMC) by oxidative carbonylation of methylamine is reported for the first time using the Pd-NaI catalyst system. The effects of various process parameters on oxidative carbonylation of methylamine are studied in detail. It is found that the selectivity pattern is strongly dependent on the type of catalyst used, the concentration of methylamine, the CO:O2 ratio, and the temperature. A possible mechanism based on the results is discussed.
