Abstract

Abstract: The decomposition of azocumene on silica surfaces in the absence of solvent is slower than in toluene solution and has a much lower radical efficiency. Radicals that escape geminate reaction can be trapped by adsorbed bisdiphenylenephenyl-allyl. The ratio of cumene to a, a-dicumyl is about five times that in toluene. Aromatized a-ortho and a- para cumyl dimers, found on14 in the reactions on silica, are formed in low yield. These ...
