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

초록

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