説明
Mesoionic anhydro-1-alkyl-3-hydroxy-1,2,4-triazolo[4,3-a]pyridinium hydroxide (6) was synthesized by selective alkylation at the N1-position of 1,2,4-triazolo[4,3-a]pyridin-3(2H)-one (8). The selectively depends on the use of a mercuric salt catalyst in combination with the trimethylsilyl derivative of 8, and its mechanistic features were also studied with reference to the benzylation of 8.
