Intermolecular rearrangement of cobalt phenylsiloxanes

Intermolecular rearrangement of cobalt phenylsiloxanes was studied. The rearrangement leads to the formation Of Compounds with metal oxide moieties in the organosiloxane Structure and is accompanied by a change in the spectral characteristics of cobalt(II), determined by the second coordination sphere of the metal. The rate-determining step is the decomposition of an intermediate complex formed upon the coordination of the metal siloxane moieties.
