Abstract

The thermally stable, terminal phosphinidene complexes [Cp†M(CO)2(η1-PNiPr2)]AlCl4 (Cp† = Cp, Cp*; M = Fe) and [Cp*M(CO)3(η1-PNiPr2)]AlCl4 (M = Cr, Mo, W) react with Ph2C[double bond, length as m-dash]N[double bond, length as m-dash]N to form terminal P-coordinated η1-phosphaazine and η3-diazaphosphaallene ligands, respectively, whereas [CpFe(CO)2(η1-PNiPr2)]AlCl4 reacts with Me3SiCHN2 affording a terminal phosphorus bound η1-phosphaalkene complex.
