ligand makes a difference: The reactivity of a dimolybdenumphosphinidenecomplex with alkenes and alkynes is substantially modified by the presence of two‐electron donors such as CO or CNXyl (Xyl=xylyl). Under these multicomponentreaction conditions, rapid formation of phosphametallacyclopentene rings takes place at room temperature. These reactions proceed in all cases with very high chemo‐ and
