Chloromethylgold(I) complexes of phosphine, phosphite, and N-heterocyclic carbene ligands are easily synthesized by reaction of trimethylsilyldiazomethane with the corresponding gold chloride precursors. Activation of these gold(I) carbenoids with a variety of chloride scavengers promotes reactivity typical of metallocarbenes in solution, namely homocoupling to ethylene, olefin cyclopropanation, and Buchner ring expansion of benzene.
三甲基硅基重氮甲烷与相应的金氯前体反应，很容易就能合成膦、亚膦酸酯和 N-杂环卡宾配体的氯甲基金(I)配合物。这些金(I)卡宾配合物用各种氯化物清除剂进行活化，促进了它们在溶液中类似于金属卡宾的反应性，即与乙烯的同偶联、烯烃环丙烷化和苯的布赫纳环扩张。
