The effect of acid in the amine exchange of N,N-dimethylformamidines has been revisited, allowing the preparation of highly electron-rich compounds that are difficult to obtain under standard conditions. The use of propargylamine as nucleophile led to the formation of substituted imidazoles.
酸在 N,N-二甲基甲脒的胺交换中的作用已被重新审视,允许制备在标准条件下难以获得的高度富电子化合物。炔丙胺作为亲核试剂的使用导致了取代咪唑的形成。
