Reactivity patterns of thermally stable, terminal, electrophilic phosphinidene complexes towards diazoalkanes: oxidation at the phosphorus centre and formation of P-bound η1-phosphaazine, η1-phosphaalkene and η3-diazaphosphaallene complexes†
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 Ph2CNN to form terminal P-coordinated η1-phosphaazine and η3-diazaphosphaallene
