Ring Cleavage of 1,2,3-Triazolium Ions with Nucleophiles

The 1,2,3-triazolium salts 1 react with a variety of nucleophiles to give products of ring scission like 2-5.The new 1,2,3-triazolium reaction most probably does not follow the pattern known in the case of isoxazolium and furazanium salts.

1,2,4-TRISUBSTITUTED 1,2,3-TRIAZOLIUM SALTS FROM NITRILIMINES AND ISOCYANIDES

Diarylnitrilimines (from 1 and triethylamine) react with alkyl isocyanides 2 to form, through proton transfer, the quaternary salts 3A.This constitutes a novel synthetic approach to the 1,2,3-triazolium ring having groups on adjacent nitrogens.
