Abstract
This invention relates to a non-aqueous method for preparing disiloxanes, copolymeric siloxanes, and cyclic siloxanes containing phenyl, higher alkyl, and certain reactive groups bonded to silicon atoms using selenium dioxide as a catalyst. The siloxanes which are formed using this method can be separated from the reaction mixture and purified.
