Palladium-catalyzed homocoupling reaction of 1-iodoalkynes: A simple and efficient synthesis of symmetrical 1,3-diynes

This paper describes a highly efficient synthetic method of symmetrical 1,3-diynes from 1-iodoalkynes in the presence of 4 mol % Pd(PPh3)(4) in DMF at room temperature under a nitrogen atmosphere without any use of additives and other metals.
