Abstract
Abstract The synthesis and characterization of an acyclic silylone (MIC) 2 Si 2 (MIC=1,3‐di(2,6‐diisopropylphenyl)‐4‐phenyl‐1,2,3‐triazol‐5‐ylidene) supported by a mesoionic carbene was reported. 2 was obtained by the reduction of (MIC)SiCl 4 1 with 4 molar equivalents of potassium graphite in toluene at −10 °C. Theoretical calculations on 2 reveal that the silicon center is highly electron‐rich and bears two lone‐pairs of electrons. Preliminary reactivity study shows that 2 can coordinate to two CuCl molecules to furnish a dinuclear copper(I) complex (MIC) 2 Si(CuCl) 2 3 .
