Half-open metallocenes with heterodienyl ligands and related compounds

This review surveys the chemistry of half-open metallocenes, half-sandwich and related compounds which include in their structure heterodienyl ligands, including oxygen, nitrogen, sulfur and phosphorus as heteroatoms. It covers the chemistry of the corresponding heterodienyls as anions, with main group, transition metals and the study of their reactivity; also some related compounds which contain heteroallyls, heterodiene or heterodienyl ligands are included.
