functional groups of several examples of 1-alkyl-4(3)-(1H-azolylmethyl) pyridinium salts 1 and 2 exemplifies a concomitant application of the arenoanalogy principle and the captodative effect in organic synthesis. A remarkably driving force by the nature of non-classical acceptor and donor heteroaromatic rings is observed upon the chemical behavior of the title compounds 1 and 2, modulating the susceptibility
与1-烷基-4(3)-(1 H-偶氮基甲基)吡啶鎓盐1和2的几个实例的己内酰胺(受体)和供体非经典官能团连接的碳原子的前所未有的自发氧化,例举了同时应用在有机合成中的种类学原理和俘获作用。在标题化合物1和2的化学行为上观察到非经典受体和供体杂芳族环的性质产生的显着驱动力,调节了亚甲基间隔基氧化成它们的氧甲基对应物5和6的敏感性。获得偶极1-烷基-3-吡啶碘甲基-3(5)-1,2,4-三唑盐内盐4 已实现。
