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(PPh(3))(4) in DMF at room temperature under a nitrogen atmosphere without any use of additives and other metals.
