By means of organometallics it is possible to control the external pore size of zeolites and introduce a new approach of shape selectivation where the molecular steri

Three types of transition metal catalyzed reactions have proven useful for organometallic polymer synthesis: (1) dehydrocoupling by self- reaction (2E-H —> H. + E-E) or by reaction with an acidic hydrogen (E-H + X-H —> H. + E-X); (2) redistribution of Si-H bonds with Si-O bonds, -. —
