This work demonstrates that significant higher yields and shorter reaction times in the Perkin synthesis of cinnamic acids are obtained in all cases investigated, when sodium acetate is replaced by caesium acetate. The caesium variant of the Perkin reaction described here should therefore be generally preferred.
这项工作表明,在所有研究案例中,当用
醋酸铯代替
醋酸钠时,
肉桂酸的珀
金合成反应都能获得更高的产率和更短的反应时间。因此,这里描述的珀
金反应的
铯变体通常更受欢迎。
