Abstract:

A simple and efficient method for the oxidative homocoupling of terminal alkynes to symmetrical 1,4-disubstituted 1,3-diynes has been developed using copper(I) iodide in a task specific basic ionic liquid, [bmim]OH under atmospheric condition without requiring any palladium compound, amine base, oxidant and organic solvent.

Keywords: Homocoupling, alkynes, 1,3-diynes, ionic liquid, copper(I) iodide
