PURPOSE:To prepare effectively by a simple operation the subject compd. having a main chain modified with an org. chain by reacting a polysiloxane compd. having an Si-Si bond with an org. unsatd. compd. in the presence of a Pd catalyst to thereby insert the org. compd. into the Si-Si bond. CONSTITUTION:A polysiloxane compd. having at least one Si-Si bond [e.g. a compd. of formula I (wherein R<1> and R<2> are each alkyl, aryl, aralkyl, alkenyl, or halogen; 2<=m+n<=6; and p>=2)] is reacted with an org. unsatd. compd. [e.g. an acetylene compd. of formula II (wherein R<3> and R<4> are each H, alkyl, aryl, heterocyclic, or silyl)] in the presence of a Pd catalyst to thereby insert the unsatd. compd. into the Si-Si bond of the polysiloxane compd., thus giving the objective compd. having a main chain of formula III {wherein A is a divalent org. group [e.g. a group of formula IV (wherein R<3> and R<4> are each as defined above)]; and (m) and(n) are each as defined above). |
