Title

Metallkomplexe in anorganischen Matrices, 5 - Katalytische Silanoxidation an einem heterogenisierten Rhodium-Komplex

Abstract
A heterogenized rhodium complex, prepared by sol-gel processing of Rh(CO)ClÄPPh2CH2CH2Si(OEt)3Ü2 and Si(OEt)4, is shown to catalyze the conversion of the silanes H(4-n)SiPh2 (n=1-3) or (HMe2Si)2O to (poly)siloxanes by air or water. Using THF as a solvent, the silanoles Ph3SiOH or Ph2Si(OH)2 are obtained instead. The reaction of phenylacetic acid or acetic acid with HSiPh3 to give silyl esters is catalyzed by the same compound.
