The oxidation of 1,1,3,3-tetraphenyl-2-methyl,1,1-di-p-tolyl-3,3-diphenyl-2-methyl1,1-dibenzyl-3,3-diphenyl-2-methyl-2-methyl1,1,3,3-tetraphenyl and 1,1-di-p-tolyl-3,3-diphenyl propenes by chromium trioxide-acetic anhydride gives the corresponding epoxide with fission products. Chromic acid in aqueous sulphuric acid brings about oxidative fission of the double bond without any rearrangement. The isolation of terephthalic acid and p-toluic acid from oxidation of 1,1-di-p-tolyl-2-methyl-3,3-diphenyl and 1,1-di-p-tolyl-3,3-diphenyl propenes was discussed. The action of perbenzoic acid on these tetra-aryl olefins was also studied.
