    摘要: Compounds of the formula Ia ##STR1## in which X and R.sup.1 to R.sup.6 are as defined in the claims, are obtainable by reacting monochlorosilanes of the formula II ##STR2## with tetrasubstituted ethylenes of the formula III ##STR3## X as Cl and Br can be replaced by ester groups of inorganic and organic acids. The compounds of the formula I and those with other ester groups are suitable especially as a protective-group reagent for hydroxyl, mercapto, carboxyl, amino and amide groups.
