The Reactions of Alkynlcyclophosphazenes with Metal Carbonyls
Abstract
The crystal structures of the free alkynlphosphazene and the tetracobalt cluster have been determined and allow for the evaluation of structural perturbation of the cyclophosphazene which occur upon coordination of the dicobalt unit to the alkyne. Electrochemical reduction of both the di-and tetracobalt species has been accomplished using cyclic voltametry. A reversible one electron reduction to a stable anion is followed by an irreversible second step. The epr spectrum of the first reduction product shows that the reduction is primarily metal based. The potentials for the first reduction are equal for the di- and tetracobalt' species indicating the absence of any significant electronic communication between the alkynl and phosphazene moieties. Keywords: Cyclophosphazenes, Alkynl complexes, Metal carbonyls, Cycloligomerization.
