When diaryl ketones were treated in DMF promoted by samarium metal with TMSCl as activator, diaryl ketones react with DMF followed by a carbene rearrangement to afford benzoins unexpectedly, with benzils were obtained as byproducts, the formation of which may be explained as a result arising from the auto-oxidation of benzoins. Further investigation found the reaction could also proceed smoothly when I〓 was used as an activator. The reaction could occur as well in SmI〓/THF, though benzoins were obtained in relatively low yields.

发现当有活化剂TMSCl存在时，金属钐能有效的促进二芳酮和DMF的发生反应，偶联后发生卡宾重排，意外地得到苯偶姻类化合物，同时伴随着少量的二芳基二酮副产物生成，我们推测二芳基二酮的生成可能从苯偶姻的自氧化而来；进一步的研究表明，用一定量的I〓活化金属钐，该反应也可以顺利的进行，并且可以得到相对更好的实验结果。
