Abstract We present an efficient methodology for the synthesis of tetrafunctionalized double‐decker silsesquioxanes via hydrosilylation reaction. An investigation of the catalytic system, olefin structure, chemical and steric surrounding of Si−H moiety in the respective reagent was carried out on the progress, selectivity and rate of hydrosilylation process. Two alternative synthetic pathways for obtaining a variety of functionalized double‐decker silsesquioxanes with high yields based on the Pt catalysts were developed. These parallel routes concern reverse Si−H and −CH=CH 2 reactive groups placement in the double‐decker silsesquioxane core. As a result, a series of new tetrasubstituted double‐decker silsesquioxanes derivatives were obtained with high yield and selectivity and comprehensively characterized in detail by spectroscopic analyses.
