- 中文摘要:
The mechanism for the photochemical reactions of o- methyl-benzaldehyde (1), o-methyl-acetophenone (2) and o- methyl-benzophenone (3) in the presence of .alpha.-phenyl-N- tert-butylnitrone (PBN) to the formation of stable nitroxyl radicals 4-6 is studied.
The nitroxyl radical product 6 can also be obtained by the thermolysis of benzocyclobutenol with PBN. Thus, the radical products were derived from a novel and regioselective 4+2 cycloaddition of the photogenerated dienol intermediate with PBN. - 英文摘要: --
