在空气和湿度稳定的N-杂环卡宾(NHC)配合物RhCl(IMES)(COD)(IMES=N，N‘-双(2，4，6-三甲基苯基)咪唑-2-亚甲基；COD=1，5-环辛二烯)，在三氟化银和1，3-丁二烯存在下，促进了金属催化的1，6-烯炔的非对映选择性[4+2+2]碳环化。
The air and moisture stable rhodium N-heterocyclic carbene (NHC) complex, RhCl(IMes)(COD) (IMes = N, N'-bis(2,4,6-trimethylphenyl) imidazole-2-ylidine; COD = 1,5-cyclooctadiene), facilitates a diastereoselective metal-catalyzed [4 + 2 + 2] carbocyclization of 1,6-enynes in the presence of silver triflate and 1,3-butadiene.
