Title
Strained Metallocenophanes: Potential Monomers for Metallopolymers
Abstract
Over the past 40 years, strained [n]metallocenophanes with their unusual structures, reactivity, and potential utility have systematically been developed and studied. In 1992, Manners et al. reported that ring-opening polymerizations (ROP) of sila[1]ferrocenophanes resulted in high-molecular-weight poly(ferrocenylsilane)s. This discovery was the starting point to significantly develop this exciting field and, to date, ROP of strained [n]metallocenophanes is one of the most elegant methods towards well-defined metallopolymers. In this seminar, some of the main results from my research will be presented and put into context. I will discuss the development of a new family of enantiopure [1]ferrocenophanes with silicon and boron in bridging position. In addition to the syntheses and structures of the obtained [1]ferrocenophanes, investigations of ROP will be discussed. An important part of my research was concerned with synthesis of highly strained [1]ruthenocenophanes with silicon and phosphorus in bridging position. These new compounds were synthesized through a multistep procedure in enantiopure form.
