METALLAPHOSPHENES AND DIPHOSPHENES
Satge, J.,Escudie, J.,Couret, C.,Ranaivonjatovo, H.,Andrianarison, M.
, p. 65 - 74 (2007/10/02)
Transient metallaphosphenes ( >M=P- ) have been obtained by exchange reactions between disilylphosphines and organometaldihalides ( M=Ge, Sn), or by thermolysis of 2-metallaphosphetanes (M=Si, Ge).They are characterized by trapping reactions with strained
