Abstract

Several methods for the generation of highly strained nonisolable cycloalkynes, for example, 1a–c, have been developed within the last decades (Scheme 1).[1] These methods typically rely on the use of metals, metal salts or complexes, organometallic compounds, strong bases, fluoride salts, or oxidizing reagents. High temperatures or irradiation of the starting material are sometimes also necessary. After their generation, the highly reactive ...
