ABSTRACT:
Ceric hydrocarbyl silyloxides are provided, as well as a process for preparing them, which comprises reacting ceric ammonium nitrate with a hydrocarbyl silanol, including a lower aliphatic silanol, under anhydrous conditions in the presence of an anhydrous base at a temperature within the range from about -30.degree. C. to about 200.degree. C. but preferably from 0.degree. to about 150.degree. C. until ceric hydrocarbyl silyloxide and the nitrate salt of the base are formed; the nitrates formed during the reaction can be separated from the reaction mixture and the ceric hydrocarbyl silyloxides isolated pure or as complexes with the solvent, or in some cases the ceric hydrocarbyl silyloxides can be used without separation from the reaction mixture in the presence of the nitrates.
