Spin-trapping of radical products of H-transfer from oxygeneous donors

Within the bachelor thesis the evaluation of experimental material focused on EPR study of spin-trapping of phenoxyl radicals on aromatic nitrosocompounds was performed. It was found that phenoxyl radicals from unhindered phenols add to nitrosogroup in the ortho-position. As a result, the nitroxyl radicals are formed. According to the structure of nitrosocompounds this nitroxyl radicals have the character either of phenoxazinoxyl radicals in the case of nitrosobenzene or derivatives of diphenylnitroxyl radical in the case of nitrosoduren. In the work is also documented the specific behavior of some phenols containing methyl group as the para substituent
