Abstract

Abstract The infra-red study of mixtures of iodine with hexynes 1, 2 and 3 shows that these hydrocarbons are electron donors, due to the presence of the triple bond. They form with iodine molecular associations of charge-transfer type. The complexes are unstable and iodine molecule, once fixed on the triple bond, reacts with it to give an addition compound. This reaction is slow in the dark but catalysed by light.
