Low-temperature Photolysis of ortho-Substituted Azidobiphenyls. Formation of Phenazines from 2,2'-Diazidobiphenyls
It was found that the unexpected phenazines were formed as minor products by the low-temperature photolysis of 2,2'-diazidobiphenyls 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.
