Arene complexes methacrylates

Iron-arene complexes are known to exhibit extremely high photoactivity as initiators. Quantum efficiencies have been found to be greater than I in the photopolymerisation of dicyanate esters. Phenylglycine derivatives have been found to be excellent co-synergists for the iron-arene complexes when used in conjunction with dyes and amines. Complexes of various types have also been proposed. Maleic anhydride-THF complexes have been used for the photopolymerisation of oligourethane acrylates while metal-ion complexes of spiropyran copolymers undergo reversible polymer precipitation. Azo and polyazo initiators have been used to make butadiene-isoprene block copolymers while charge-transfer complexes of morpholine-chlorine induce the radical polymerisation of methyl methacrylate. The presence of zinc chloride enhances the... 

An [(arene)RuCl2]2 complex with a methacrylate side chain has also been prepared in two steps using commercially available starting materials. This complex reacts with PPhs, pyridine, or toluidine to give the corresponding mononuclear adducts which were immobilized by co-polymerization with divinylbenzene (DVB) or ethyleneglycol...
