The hydrogenolysis and dimerization of iodoalkanes were catalyzed by Pd in the presence of an appropriate reducing agent.Hydrazine was found to be effective for the coupling of 1-iodoeicosane to give tetracontane, C40H82, in a 74 percent yield.The yield of the coupling product decreased with the decrease of the number of the carbon atoms in the 1-iodoalkanes.Both alkylhydrazines and alkenes were shown not to take part in the reaction as a reaction intermediate.
