As facile precursors for nonstabilized pyridinium methylides N-(trimethylsilylmethyl)pyridinium triflates were synthesized. Cesium fluoride induced desilylation of the precursors liberated the nonstabilized pyridinium methylides which were trapped as the cycloadducts to dimethyl acetylenedicarboxylate.
作为非稳定吡啶鎓甲化物的简易前体,合成了 N-(三甲基硅甲基)吡啶鎓三氯酸盐。在氟化铯的诱导下,前体发生脱硅反应,释放出非稳定的吡啶鎓甲化物,这些甲化物作为乙炔二甲酸二甲酯的环加成物被捕获。
