We report herein an efficient procedure for the synthesis of new POSS derivatives, as a multifunctional reagents. This study concerns the incompletely condensed silsesquioxanes and germasilsesqiuoxanes with vinylsubstituted silyl and germyl functional groups which allow to further modification. Furthermore, our experiments have been extended to synthesis new subclass of completely condensed vinylgermasilsesquioxanes. These hybrid building blocks were obtained selectively within a few hours and were isolated with excellent yields.
