合成了一种高效的环（烷基）（氨基）卡宾铱配合物（C-2），用于甲醇直接羰基化合成乙酸甲酯（MA）。与以前的结果相比，C-2催化甲醇羰基化合成MA在较低温度（120 °C）下进行得相当好。即使在转化率高（81%）时，反应也显示出对MA的优异选择性（96%）。通过化学计量实验和理论计算对反应过程进行了研究。
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.
