Reactions with excess ethyl diazoacetate proceeded slowly and with concomitant denitrogenation to give complexes [MoMCp(μ-η²_P,C:κ²_P,O-PR*CHCO₂Et)(CO)₅], which display a bridging phosphaalkene ligand in a novel μ-η²:κ² coordination mode, while reactions with other diazoalkanes resulted only in the decomposition of the organic reagent.
