the green, simple and highly efficient synthesis of bis(indolyl)methanes and 3,3′-(arylmethylene)bis(4-hydroxycoumarins). This methodology has some advantages such as short reaction times, environmentally friendly conditions, easy work-up, and excellent yields. This catalyst can be easily separated and re-used without any appreciable loss in its activity.
P 4 VPy-CuO纳米颗粒作为新型固体催化剂,采用超声辐照法合成,并通过X射线衍射(XRD),扫描电子显微镜(SEM),透射电子显微镜(TEM)和傅立叶变换红外光谱(FT-IR)表征)光谱学。制备的催化剂用于绿色,简单,高效的双(吲哚基)甲烷和3,3'-(芳基亚甲基)双(4-羟基香豆素)的合成。该方法具有一些优点,例如反应时间短,环境友好的条件,易于后处理和优异的收率。该催化剂可以容易地分离和重复使用,而其活性没有任何明显的损失。
