Abstract

In this paper, an efficient method for the preparation of new silsesquioxanes with mixed functional groups of general formula (RSiMe2O)n(ViSiMe2O)8−nSi8O12 is described. The proposed protocols are based on hydrosilylation of octakis(dimethylvinylsiloxy)octasilsesquioxane ((ViSiMe2O)8Si8O12) with unsymmetrical disiloxanes. As an example of possible modification of (RSiMe2O)n(ViSiMe2O)8−nSi8O12 derivatives, a thiol addition was distinguished. A series of silsesquioxane compounds with a variety of functional groups (silylamine, epoxy, and chlorine) were obtained and characterized. The obtained compounds can be considered as novel multi-substituted materials, which significantly increase the possibility of the synthesis and design of new functional materials.
