The subject of the invention is the method of synthesis of fluoracarbofunctional cage silsesquioxanes of the general formula in which&#x2022;Rstands for HCF(CF)(CH)mO(CH)Si(CH)O or HCF(CF)(CH)O(CH)group in which n=1-12, m=1-4;&#x2022;R, R, R, R, R, R, Rcan be the same as Ror different from it and stand all either for the (C-C) alkyl group or any aryl group, based on hydrosilylation of fluoroalkyl-allyl ether with an appropriate hydrogen-silsesquioxane in the presence of siloxide rhodium complex [{Rh(OSiMe)(cod)}] as a catalyst.

The subjects of the invention are new heterogenized rhodium complexes, the methods of their synthesis and their application as catalysts for synthesis of organosilicon compounds by hydrosilylation. The subject of the invention are new siloxide rhodium(I) complexes immobilised on the silica surface, of the general formula 1. [(&#x2261;SiO)(L)Rh(diene)] The second subject of the invention is the method of synthesis of the new rhodium complexes of the general formula 1. The third subject of the invention is the method of obtaining the organosilicon compounds in the reaction of hydrosilylation between the selected alkenes or functionalised alkenes containing the terminal C&#x2550;C bond and the appropriate compounds containing the Si&#x2550;H bond selected from silanes, (poly)siloxanes and (poly)carbosiloxanes, in the presence of heterogenized rhodium catalysts, of the general formula 1.
