2-(Phenylazo)propene (517, R1 = Me; R2 = H) and 1-(phenylazo)cyclopentene [517, R1,R2 = (CH2)3] react with N-aminophthalimide (516), in the presence of lead(IV) acetate, to give 2-phenyl-2H-1,2,3-triazoles 520 in moderate yields (Scheme 180).[508] A probable mechanism for this reaction involves the initial formation of the azimine intermediate 518, 1,5-electrocyclization to the 2,5-dihydro-1H-triazole 519, and, finally, 1,2-elimination of phthalimide.
