  • Part of the planned dissertation of C. Stern. We would like to thank Prof. Dr. H. Vahrenkamp for access to the X-ray diffractometer in Freiburg. We are grateful to the Ministère de l'Enseignement Supérieur et de la Recherche (Paris) for a post-doctoral grant to U. B., to the Centre National de la Recherche Scientifique, the Commission of the European Communities (contract CHRX-CT93-0277), and the Alexander von Humboldt-Stiftung (award to P. B.) for financial support, and Johnson Matthey PLC for a generous loan of PtCl2.

Abstract

original image

The silylene complexes 1 are stabilized by the electron-deficient metal fragment PtL2 rather than by a more usual electron-donating group. The base-stabilized silylene complex 2 is formed in the reaction of [Fe(CO)4{P(OEt)3}] with HSi(NMe2)3 as a result of an unprecedented exchange of OEt and NMe2 ligand substituents.
