Abstract

This feature article provides an overview of the synthesis and reactivity of functionalized cycloheptatrienyl–cyclopentadienyl transition metal sandwich complexes of the type [(η7-C7H7)M(η5-C5H5)] (M = group 4, 5 or 6 metal), which can be used as building blocks for the preparation of metallopolymers and polymetallic complexes. Emphasis is placed on 16-electron group 4 complexes (M = Ti, Zr, Hf) and their reactivity towards σ-donor/π-acceptor ligands, which indicates that these complexes bear a close resemblance to Lewis acidic M+IV complexes. Based on theoretical calculations, this behavior can be mainly attributed to the strong and appreciably covalent metal–cycloheptatrienyl interaction with the cycloheptatrienyl ring acting more as a −3 ligand than as a +1 ligand in these mixed ring complexes.
