A novel α-diazotrifluoroethyl sulfonium salt was prepared, and it was applied in Rh-catalyzed three-component [2+1+2] cycloadditions for the first time, affording various imidazo[1,5-a] N-heterocycles under mild conditions. This strategy involved a unique trifluoromethyl Rh-carbynoid (CF3C+=Rh), wherein three new chemical bonds were forged at the α-carbon of trifluoromethyl in a single step.
