Title
New approach to synthesis of functionalised silsesquioxanes via hydrosilylation
Abstract

Synthesis of functionalised silsesquioxanes was carried out in the process of hydrosilylation catalysed by platinum complexes immobilised in ionic liquids. Platinum complexes at different oxidation states in the medium of three ionic liquids. Results of the study indicate that activity of catalytic systems investigated strongly depends on the type of ionic liquid used for metal complex immobilisation as well as on the kind of olefin subjected to hydrosilylation. The most effective catalytic system for all reactions studied was PtCl4 in 1,2,3-trimethylimmidazolium methylsulfate.
