Recently we reported on the first [l]boraferrocenophanes which represent the first examples of ansa-metallocenes with a bridging first row element. Due to the small size of the bridging boron atom these molecules are highly strained and thus exceptionally reactive, which was already proven by i) their ability t0 undergo thermally induced ring-opening polymerisation (ROP) with formation of the first poly(ferrpcenyl)boranes and il) an unprecedented ironcyclopentadienyl cleavage reaction yielding novel boron-bridged heterodinuclear half-sandwich complexes. The present proposal aims at establishing a wide range of strained complexes with two aromatic boron-bridged ligands of various transition metals such as vanadium, chromium, molybdenum, tungsten; and ruthenium. Furthermore, the potentially useful chemistry of strained [l]borarnstallooenophanes and related complexes will be further exploited. The synthesis of soluble, high-molecular organometallic polymers is a main target as especially poly(ferrocenes) are wall known to display physical properties which could allow for their application for example in nanostructured magnetic materials or charge-transport materials. Besides, the potential propensity of the endocyclic B-C bond to undergo oxidative additions to low-valent transition metal centres will be explored. This could provide i) a novel route to unusual dinuclear boryl complexes and U) an alternative access to poly(ferrocenyl)boranes and related compounds via a transition metal catalysed process.
