Abstract
Vinylidenes featuring heavier group 14 elements (>E = E:, E = Si, Ge, Sn, Pb) represent a unique class of compounds in which the two group 14 centers exist in distinct oxidation (+II and 0) and coordination states. Owing to the presence of a reactive group 14 element in a formal zero oxidation state, most of these vinylidenes are mainly stabilized using Lewis bases such as N-heterocyclic carbenes (NHC), silylenes (NHSi), etc. These stabilization strategies have enabled the isolation of a growing number of homo- and hetero-vinylidenes, garnering significant interest from the synthetic main group chemistry community. This review provides a comprehensive overview of the recent developments in the synthesis, structural characterization, and reactivity of heavier vinylidenes. The reactivity studies of these vinylidenes include cycloadditions, nucleophilic substitution, oxidative addition, group transfer reactions, etc.
期刊介绍：
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
