NEW MATERIAL:The compound of formula I (X is 1-12C perfluoroalkyl, perfluoroalkoxy, pentafluorophenyl, substituted phenyldimethylsilyl, polyfluoroalkylmethyloxycarbonyl, etc.; l is 2-4; m and n are positive integer; m+n is 3-6; n/m is 0.2-5.0). USE:An intermediate for the preparation of a durable silicone rubber, oxygen-enriching membrane, etc. PREPARATION:The compound of formula I can be prepared e.g. by dissolving dimethyldichlorosilane and the compound of formula II (e.g. 3,3,3-trifluoropropylmethyldichlorosilane) in a solvent such as ether, and adding the solution dropwise in water under the flow of argon gas to effect the cohydrolysis of the components.
