摘要：

The reactions of [Pt(CH2=CH2)(PPh3)(2)] and [Au(C6F5)(SC4H8)] with diazoalkanes have been performed under FAB conditions. The formation of the carbene species [Pt(=CHCO2Et)-(PPh3)(2)] and [Au(=CPh2)(C6F5)], respectively, which are the key reaction intermediates and which were not detected in solution using other analytical tools, has been revealed by modern mass spectrometric techniques. Since the reaction products obtained by FAB MS were the same as those obtained in solution, mass spectrometry, providing an entry to the detection of highly reactive intermediates, may give also mechanistic information otherwise not achievable.
