The title, thermally stable, heterocarbanions (2a, 2b) were generated upon respective exposure of conjugate acids 4(a,b) to a KNH2/liq. NH3 system and were shown (NMR) to possess (2a more than 2b) distinct elements of paratropicity.
分别将共轭酸4(a,b)暴露于KNH 2 / liq后,生成标题为热稳定的杂碳负离子(2a,2b)。NH 3体系显示(NMR)具有(2a大于2b)的顺温性不同元素。
