Matsuda, Yoshiro published the artcileReaction of 4-amino-1,2,4-triazolium salts with polarized olefins, Name: 4-Amino-1-methyl-4H-1,2,4-triazol-1-ium iodide, the main research area is aminotriazolium salt cyclization polarized olefin; triazolium salt amino cyclization polarized olefin; betaine mesomeric preparation; triazolopyrazole preparation.
The reaction of 4-amino-1,2,4-triazolium salts I (R = Me, CH2Ph, X = iodo, Br) with polarized olefins EtOCH:CR1CO2Et (R1 = CO2Et, NO2) and (MeS)2C:CXY (X = CO2Me, Y = cyano) in the presence of K2CO3 in EtOH or DMSO directly yielded the back-donated 1,6-cyclization products, mesomeric betaines II (R1 = CO2Et, NO2, R2 = H; R1 = cyano, R2 = SMe) via N-vinylimino ylides, while the reaction of the salts I with polarized olefins (MeS)2C:CXY (X = H, Y = NO2; X = SO2Ph, Y = cyano) gave the 1,5-dipolar cyclization products, pyrazoles III and [1,2,4]-triazolo[4,3-b]pyrazole IV.
