This article may be used for non-commercial purposes in accordance with Thieme Terms and Conditions for self-archivingMetal-vinylidenes, generated by treatment of terminal alkynes with transition metals, are very useful intermediates in modern synthetic chemistry as shown by the high number of transformations in which they are involved. When a metal-vinylidene is generated in the presence of an oxidant, its immediate oxidation to a ketene intermediate occurred. In this short review, recent synthetic applications of the oxidation of alkynes via ketene intermediates from initially formed metal-vinylidenes are highlighted.eng© Georg Thieme Verlag Stuttgart · New York.
