The synthesis of allyl ether functionalized siloxane monomers under ultrasonic irradiation at ambient conditions.
The novel class of cationic UV-curable allyl ether functionalized siloxane monomers type CH2=CH-CH2-O-R-O-Si(CH3)3 and type CH2=CH-CH2-O-R-O-Si(CH3)2-O-R-CH2-CH=CH2 have been synthesized in excellent yields in short times at ambient temperature conditions in the absence of any added catalyst by the classical silylation reactions of homoallyloxyalcohols with chlorosilanes under ultrasonic irradiation.
