Alkoxydiazenium salts

Interaction of o-dialkylamino-substituted benzalaniline [144, RR = (CH2)5] with alkoxydiazenium salt [RR1 = (CH2)5], followed by borohydride reduction, yields the rare 1,5-fused triazoline 145 the course of reaction is not influenced by the o-dialkylamino group. However, with the...

Alkyl- and aryl-triazolium compounds are formed mostly by quaternization of preformed triazoles, more rarely by rearrangement of oxadiazoles proceeding through acylamidrazone intermediates. An unusual method (Scheme 136) is the addition of the alkoxydiazenium fluoroborate (312) to the Schiff base (313) to form the triazolium salt (314) through a mechanism that may involve a triazolidine intermediate (315) (69CB3176).
