SYNTHESIS OF ORGANOSILICON DERIVATIVES OF ACRYLIC ACIDS

A study of the reactions of organohydrochlorosilanes with allyl acrylate showed that the addition proceeds at the β-position in all cases.The acrylate-containing chlorosilanes react with acetic anhydride to give quantitative yield of the acetoxy derivatives.Study of the hydrolysis of the chloro and acetoxy derivatives showed the feasibility of the direct synthesis of the corresponding silanols.The reactivity of these compounds was studied.
