摘要：

The reduced electrophilicity of the Ti center resulting from Cp* ligands and sp2 hybridization of the ring‐C atoms influences the stability of 1 (XN, P) in such a way that 1‐aza‐ and 1‐phospha‐2‐titanacclobut‐4‐enes could be characterized by X‐ray structure analysis for the first time. The metallacycles 1 are formed by trapping the [Cp *2TiCCH2] intermediate with tBuCX (XN or P); however, the mechanisms of these reactions differ. (Figure Presented.)
