22 Inorganic and organometallic polymers

Abstract

In 2004, numerous advances were made in the area of inorganic polymer science. In particular, evidence for the presence of Si–H end groups from the Wurtz coupling of dichlorosilanes was obtained. A new mechanism of dehydropolymerization of stannanes was proposed. The first π-conjugated polymers featuring PP bonds in the main chain were prepared. In the area of transition metal macromolecules, the first examples of ruthenocenylsilane and bis(benzene)chromium polymers have been obtained by using ring-opening polymerization techniques. Silametallacyclobutanes have been polymerized. In addition, the photolytic living anionic ring-opening polymerization of silicon bridged [1]ferrocenophanes has been reported.
