Selective functionalization of (CH2=CH)8Si8O12 1 by the addition of dichlorocarbene to vinyl double bonds giving (C3H3)8Si8O12 2 or (C2H3)4(C3H3Cl2)4Si8O12 3 respectively is described. The dichlorocarbene was generated from CHCl3 in phase transfer catalytic system (PTC). Furthermore, (PhCH2CH2)8Si8O12 4 has been synthesized by Friedel-Crafts alkylation reaction of benzene with 1 using AlCl3 as catalyst.
