Tert-butyl-diphenylmethylnitroxyl radical formation with the reaction of triphenylbismuth dicrotonate and C-phenyl-N-tert-butylnitrone in benzene

Abstract

Decomposition of triphenylbismuth dicrotonate in diffused light in bensene in the presence of spin trap of C-phenyl-N-tert-butylnitrone leads to formation of phenyl radicals which are registered as the adduct PhCH(Ph)N(O•)Bu-t.Triphenylbismuth dicrotonate Ph3Bi(O2CCH=CHCH3)2 in benzene solition in the presence of C-phenyl-N-tert-butylnitrone PhCH=N(O)Bu-t decomposes in light. An adduct of phenyl radical and spin trap PhCH(Ph)N(O•)Bu-t was registered by ESR method.
