conditions. The catalysts can be easily recovered and reused several times without significant loss in activity. A simple and highly efficient approach to the synthesis of bis(naphthol)methane (BNM) and bis(indolyl)methane (BIM) derivatives has been developed. In the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO)-based ionic liquid catalysts, which are environmental friendly, inexpensive, and recyclable
摘要 已经开发了一种简单高效的合成双(萘酚)甲烷(BNM)和双(吲哚基)甲烷(BIM)衍生物的方法。在环境友好,廉价且可循环使用的1,4-二氮杂双环[2.2.2]辛烷(DABCO)基离子液体催化剂的存在下,该反应在溶剂下可在短时间内以良好的产率获得优异的相应产物无条件。催化剂可以容易地回收和重复使用几次,而活性没有明显损失。 已经开发了一种简单高效的合成双(萘酚)甲烷(BNM)和双(吲哚基)甲烷(BIM)衍生物的方法。在环境友好,廉价且可循环使用的1,4-二氮杂双环[2.2.2]辛烷(DABCO)基离子液体催化剂的存在下,该反应在溶剂下可在短时间内以良好的产率获得优异的相应产物无条件。催化剂可以容易地回收和重复使用几次,而活性没有明显损失。
