在无催化剂条件下,以离子液体[BPY][BF4]为溶剂,以易得的芳香醛和达米酮为原料,一锅法合成了一系列2H-氧杂蒽类化合物,通过IR和1 H NMR R对产物进行了结构表征,为这类化合物提供了简便高效的绿色合成方法.
In the absence of catalyst, a series of 2H-xanthenes were synthesized by one-pot method from the readily available aromatic aldehydes and diketones using ionic liquid [BPY] [BF4] as solvent and IR and 1 H NMR R structural characterization of the product, for these compounds provides a simple and efficient method of green synthesis.
