The organic compounds of iodine(III) with the general formula ArIL2 (Ar = aryl, L = (pseudo) halides) degrade homolytically upon irradiation or heating to the corresponding monovalent iodine compound (ArI) and the radicals L• . If the latter contains a functional group, they can be used to initiate the polymerization of vinyl monomers to afford chain end-functionalized linear polymers. When "conventional" monovinyl monomers are copolymerized with di- or multivinyl monomers (crosslinkers) in the presence of relatively high concentrations of rapidly decomposing ArIL2 compounds, highly branched polymers are formed that contain multiple chain-end functionalities derived from the radicals L• . The ArIL2 compounds are also known to transfer its ligands to various olefins such as styrene and cyclohexene under mild conditions. This dissertation focuses on designing a new class of hypervalent (HV) iodine(III) compounds that are explosives at elevated temperatures and were used to modify rubber surfaces to make them energetic. Also, utilizing the existing HV iodine(III) as radical initiators to prepare functional polymers.
