説明
<jats:title>Abstract</jats:title><jats:p>A neutral silylyne complex with a Cr≡Si triple bond was prepared by dehydrogenation of a chromium silylene complex with Cr−H and Si−H bonds, and was isolated as monomeric crystals, unlike dimeric forms of its tungsten and molybdenum congeners. The strong Cr(<jats:italic>δ</jats:italic>−)−Si(<jats:italic>δ</jats:italic>+) bond polarity was revealed by the reaction with MeOH and DFT calculations. The chromium silylyne complex reacted with H<jats:sub>2</jats:sub> under LED (365 nm) irradiation to reproduce the precursor silylene complex with a (H)Cr=Si(H) moiety, as a result of 1,2‐H−H addition across the Cr≡Si triple bond. Similarly, the chromium silylyne complex reacted with benzene under irradiation to afford an 1,2‐addition product with a (H)Cr=Si(Ph) moiety, via benzene C−H bond activation accompanied by Si−C bond forming.</jats:p>
