Two-step functionalization of octakis(dimethylvinylsilyloxy)silsesquioxane via silylative coupling, resulting in the formation of 6 (CH2=CH–SiMe2–)8−n(R1–C6H4–CH=CH–SiMe2–)nSi8O12 and 7 (R2–C6H4–CH=CH–SiMe2–)8−n(R1–C6H4–CH=CH–SiMe2–)nSi8O12). Reaction conditions: dichloromethane (DCM), [RuHCl(CO)(SIDip)(PCy3)]/CuCl, [Ru]:[Cu] = 1:5, [Ru] = 1.00 mol%, reflux, argon. The molecules designed to be obtained by the reaction’s stoichiometry are presented.
