Functionalized unsaturated derivatives of (dimethylvinylgermoxy)heptasubstituted silsesquioxanes and the method of their synthesis

A new functionalized polyhedral octavinylsilsesquioxanes having the general formula 1, in which Rdenotes: (1) any aryl group other than a non-substituted phenyl or a phenyl substituted in position four with a halogen or the groups-trimethylsilylethynyl, 4,4,5,5-tetramethyl-1,3-dioxaborolane-2-yl, 3,4-dimethoxyphenyl, 3',5&#x2032;-bis(methoxycarbonyl)phenyl or benzo[d][1,3]-dioxol-5-yl; (2) any heteroaryl group; or (3) groups including coupled aromatic rings. Additionally, a method to obtain new and known functionalized polyhedral octavinylsilsesquioxanes having the general formula 1, by the silylating coupling of octavinylsilsesquioxane with olefins in the presence of a ruthenium complex catalyst.
