Photochemical decomposition of 1,2,3,4-tetrahydro-1-naphthyl hydroperoxide. Photocatalytic effects of 3d transition metal 2,4-pentanedionates

The photochemical decomposition of 1,2,3,4-tetrahydro-1-naphthyl hydroperoxide (THP) in benzene has been investigated. The kinetics of the formation of the main products and of the removal of THP have been measured. It has been demonstrated that the solvent participates in the overall mechanism of THP photolysis. The effects of Fe(III), Co(III), Co(II), Mn(III), Cu(II), Cr(III) and Ni(II) 2,4-pentanedionates on the kinetics of THP photolysis and the formation of the main products have been investigated. Fe(III) and Co(III) 2,4-pentanedionates act as catalysts of the photochemical decomposition of THP.
