The synthesis of 1-(2-propynyl)pyridinium salts 3 described. Compounds 3 react with a second pyridine molecule, in the presence of the corresponding hydrochloride, to form products of type 4, Certain bases cause the 1-(2-propynyl)pyridinium salts 3 to rearrange into 1-propadienylpyridinium salts. 5. Diethylamine converts compounds 3 into 1-acetonylpyridinium salts 8. Moreover, treatment of 3 or 5 with
描述了1-(2-丙炔基)吡啶鎓盐3的合成。在相应的盐酸盐存在下,化合物3与第二个吡啶分子反应形成4型产物。某些碱会导致1-(2-丙炔基)吡啶鎓盐3重排为1-丙烯二吡啶鎓盐。5。二乙胺将化合物3转化为1-丙酮基吡啶鎓盐8。此外,用甲醇钠处理3或5得到9型烯醇醚,可以水解为酮8。还报道了向某些不饱和化合物中添加溴。
