✦ Synopsis

Palladium-Catalyzed Insertion of 1,2-and 1,4-Quinones into Si-Si Bonds and Its Application to the Modification of Si-Si-Bond-Containing Polymers.

-The title reaction proceeds in the presence of palladium-phosphine catalysts, PdCl 2 (PEt 3 ) 2 is the most efficient, to give various 1,2-and 1,4-bis(siloxy) aromatic compounds. This process is applied to the modification of Si-Si bond-containing polymers by direct insertion of quinones into their backbones. Since the modified polymers exhibit unique photochemical and thermal properties, the present reactions provide a new methodology for controlling the physicochemical properties of Si-Si bond containing polymers. -(YAMASHITA, H.;
