RT Journal Article T1 Oxidation of Alkynes via Catalytic Metal-Vinylidenes A1 Álvarez Pérez, Andrea A1 Saá Rodríguez, Carlos A1 Varela Carrete, Jesús Ángel K1 Amides K1 Cyclization K1 Esters K1 β-Lactams K1 Ketenes K1 Vinylidenes AB Metal-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.
