The reaction of 2-chloro-N-phenacylpyridinium salts with diazonium salts in the presence of bases was studied for the first time. It was demonstrated that this reaction leads to the formation of [1,2,4]triazolo[4,3-a]pyridinium salts. It was shown that substitution of the pyridine with a thiazole moiety leads to a similar cyclization.
首次研究了在碱存在下2-氯-N-苯并吡啶鎓盐与重氮盐的反应。已证明该反应导致[1,2,4]三唑并[4,3- a ]吡啶鎓盐的形成。已表明用噻唑部分取代吡啶导致类似的环化。
