Synthesis of new monofunctional organosilicon molecules - Prospective efficient stoppers for the design of new siloxane polymers of unusual architecture

New previously unknown bulk polyfunctional organosilanes with rigid molecular structure have been synthesized. The molecular structures of compounds 3 and 4 were defined by X-ray data. The possibility of use of prepared compound 3 as blocking agent for preparation of polyrotaxanes was demonstrated on model reaction.
