The first [2+2] cycloadduct of the transition metal silylene complex and nitrile was synthesized by the reaction of titanium silylidene and benzonitrile. Only one regioisomer was exclusively isolated, in which the C atom of the nitrile group was bound to titanium whereas the N atom was bound to silicon, which was explained by steric effects. Based on its NMR spectroscopic and X‐ray crystallographic data, this [2+2] cycloadduct was classified as possessing predominantly metallacycle resonance structure.
