PhMe2SiLi reacts with tertiary amides, RCONMe2, to give a carbene, RCNMe2, or an equivalent carbenoid, which gives enediamines, R(Me2N)CC(NMe2)R, in the absence of a strong nucleophile, but is attacked by strong nucleophiles, NuLi, to give lithium reagents R(Me2N)CLiNu.
PhMe2SiLi 与叔酰胺 RCONMe2 反应生成碳烯 RCNMe2 或等效的类碳化物,在没有强亲核物的情况下生成烯二胺 R(Me2N)CC(NMe2)R,但在强亲核物 NuLi 的作用下生成锂试剂 R(Me2N)CLiNu。
