in a rigid matrix. The phenazine formation results from the 1,1′-C–C bond fission of the biphenyl nucleus and suggests the aziridine intermediates. The low-temperature photolysis of 2-azido-2′-methylbiphenyl and 2-azido-2′,4′,6′-trimethylbiphenyl leads to the triplet-derived phenanthridine derivatives as major products.
发现意外的吩嗪是通过 2,2'-二叠氮联苯在刚性基质中的低温光解形成的次要产物。吩嗪的形成源于联苯核的 1,1'-C-C 键裂变,并暗示了氮丙啶中间体。2-叠氮基-2'-甲基联苯和2-叠氮基-2',4',6'-三甲基联苯的低温光解导致三联体衍生的菲啶衍生物作为主要产物。
