Synthesis and Properties of Peroxy Ester Having a Benzophenone Chromophore

Article abstract of DOI:10.1246/bcsj.64.3538

Diperoxy esters having a benzophenone chromophore have been successfully synthesized from the reaction of 3-chloro-3-phenylphthalide (1) with 2,5-dihydroperoxy-3-hexyne (4a) or 2,5-dihydroperoxy-2,5-dimethylhexane (4b).The corresponding diperoxy esters had a UV absorption above 300 nm.The free radicals produced during the photolysis of those compounds initiated the radical polymerization of methyl methacrylate at room temperature under UV light.
