Reactions of fluoroalkanoyl peroxides [RFCO2O2CRF, RF=C3F7, C6F13, CF (CF3) OC3F7, CF (CF3) OCF2CF (CF3) OC3F7] with vinylsilanes [R3SiCH=CH2, R=CH3, OCH3, OC2H5] and allylsilanes [R3SiCH2CH=CH2, R=CH3, OCH3, OC2H5, OSi (CH3) 3] were studies, Fluoroalkyl radicals (RF·), produced by the thermal decomposition of fluoroalkanoyl peroxides, added to vinylsilanes to give fluorine-containing silicon oligomers [RF- (CH2-CHSiR3) n1-RF, n1=2, 3]. Allylsilanes reacted with fluoroalkanoyl peroxides to give 1 : 1 adducts [R3SiCH2CH (OCORF) CH2RF] without oligomer formation. The synthesis of these new fluorine-containing silicon compounds is possible under very mild conditions (3040°C) to give excellent to moderate yields. Products bearing alkoxy groups were found particularly useful for surface active substances and have good water-and oil-repellency.
