Abstract

Abstract Mono-and polydentate phosphanes Me(4-x)E(CH2PMe2)x (E = Si, Sn) are prepared by the reaction of LiCH2PMe2 with Me(4-x)EClx. They are easily deprotonated at the methylen carbon atom. The preparation of BrCH2CMe2CH2PMe2 and Me2C(CH2PMe2)2 is also described. The complex formation ability is shown by the isolation of the tetrahedral nickel(0) complex [Me2Si(CH2PMe2)2]2Ni, where the diphosphane acts as a bidentate chelating ligand with heteroelement bridges. The new compounds are characterized by means of NMR spectroscopy.
