An efficient cyclic(alkyl)(amino) carbene iridium complex (C-2) was developed for methanol carbonylation to methyl acetate (MA) directly. Compared with previous results, methanol carbonylation to MA catalyzed by C-2 was performed quite well at a low temperature (120 °C). The reaction showed excellent selectivity toward MA (96%) even when the conversion was high (81%). The reaction processes were also investigated by stoichiometric experiments and theoretical calculations.

环状（烷基）（氨基）碳烯铱配合物催化甲醇羰基化为乙酸甲酯

开发了一种有效的环状（烷基）（氨基）卡宾铱配合物（C-2），用于甲醇羰基化直接合成乙酸甲酯（MA）。与以前的结果相比，C-2催化的甲醇羰基化反应在低温（120°C）下进行得很好。即使当转化率高（81％）时，反应也显示出对MA（96％）的优异选择性。还通过化学计量实验和理论计算研究了反应过程。
