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.

Two stereochemically defined diazetine N,N'-dioxides were synthesized. Thermal decomposition at 200 degrees C resulted in 95% retention of stereochemistry in the alkene product relative to the starting stereochemistry. These results suggest that decomposition occurs via cleavage of the two C-N bonds either simultaneously or in rapid succession.
