A series of reactionsbetween 5-nitroso-1,3-diphenyltetrazolium tetrafluoroborate and methoxybenzenes, amines, thiols, sulfoxides, and sulfides, most of which are generally accepted as being inert ...
Photochemistry of mesoionic compounds. Photochemical conversion of 5-azido-1,3-diaryltetrazolium salts to novel tricyclic mesoions with a tetrazolo[1,5-<i>a</i>]benzimidazole skeleton
A new type of tetrazolium-5-amide mesoions 2 with a tricyclic tetrazolo[1,5-a]benzimidazole skeleton has been synthesized via photolysis of 5-azido-1,3-diaryltetrazolium salts 1.

The photochemical reactions of nitrogen-rich mesoionic 1,3-diphenyltetrazolium heterocycles and related compounds
Photochemical reactions of azo and triazo derivatives of mesoionic 1,3-diphenyltetrazolium heterocycles and related compounds were studied. The reaction paths were found to depend markedly on the types of substrate, substituent and reaction solvent giving diverse products. Upon irradiation of the 1,1′3,3′-tetraphenylazoditetrazolium salt 1, the addition of hydrogen and acetone to the NN bond was observed
New mesoionic amides 4 and 5 with novel tricyclic ring systems have been synthesized by the photolysis of a 5-azido-1-mesityl-3-phenyltetrazolium salt 1c via the corresponding triplet nitrene inter mediate. The structure of 5 has been determined by X-ray crystallography.
