Synthesis of N-Vinyl-1,2,3-triazole Derivatives

Nitro-substituted N-vinyl-1,2,3-triazole derivatives were synthesized by the vinyl exchange reaction. The process was promoted by the catalytic system mercury(II) acetate-trifluoroacetic acid. This system is universal, and it can be used in the synthesis of vinylazoles having two, three, and four nitrogen atoms in the ring. in the ring.
