Abstract

Abstract : Pentaphosphaferrocene, [Cp*Fe(η 5 -P5 )], was used as an air-stable source of polyphosphorus units to synthesize a novel bis(germylene)-functionalized transition metal polyphosphide complex, which further undergoes a unique constitutional isomerization. Abstract : Pentaphosphaferrocene, [Cp*Fe(η 5 -P5 )] (Cp* = η 5 -C5 Me5 ), was used as a polyphosphorus source to obtain germylene–polyphosphide complexes. A stepwise reactivity was observed between the di-germylene, [LGe–GeL] (L = {PhC(N t Bu)2 }), and [Cp*Fe(η 5 -P5 )]. Firstly, reductive homolytic cleavage of the Ge–Ge single bond in [LGe–GeL] led to [(LGe)2 {(μ, η 4 -P5 )FeCp*}]. This complex showed an unprecedented isomerization.
