Perfluoroalkyl ether substituted silicon compounds of the type (CH3)nSi(R_fOR_f)_4-n (n=1-3) and HSi(R_fOR_f)3 where R_fOR_f=F(CF3)2COCF2CF2have been synthesized in good yields (64-81percent) through the reaction between the organolithium reagent R_fOR_fLi and the corresponding silicon chloride.The stability of these compounds towards acid, base and aqueous media were studied and the ease of cleavage of the Si-R_fOR_f bond was found to be in the order HSi(R_fOR_f)3>CH3Si(R_fOR_f)3>(CH3)2Si(R_fOR_f)2>(CH3)3SiR_fOR_f.The influence of the R_fOR_f group on some properties of these compounds is also described.
