The previously unknown symmetrical dihalides 1, l-diiodopropane and l, l-diiodo-2- methylpropane, have been synthesized by treatment of the corresponding diazoalkane with iodine. The new asymmetrical dihalides, 1-chloro-1-iodopropane and 1-bromo-1- iodopropane, have been obtained by halodecarboxylation of a-chlorobutyric and a- bromobutyric acid, respectively, with lead tetraacetate in the presence of iodine.
