摘要

以4-羟基香豆素为原料，在乙醇存在下用苯甲醛处理，采用微波合成方法制备了苄基双-4-羟基香豆素(BBHC)。采用IR、1h - nmr、MS和元素分析对BBHC的形成进行了表征。用x射线单晶衍射测定了其晶体结构。与传统加热方法合成的BBHC相比，其结构中没有异构现象。

Microwave-Assisted Synthesis and Crystal Structure of 3',3-Benzylidene-Bis-4-Hydroxycoumarin

benzylidene-bis-4-hydroxycoumarin(BBHC) was prepared by using a microwave synthetic route in which 4- hydroxycoumarin was treated with benzaldehyde in the presence of ethanol. The formation of BBHC was characterized by IR, 1 H-NMR, MS and elemental analysis. Its crystal structure was determined by X-ray single crystal diffraction. Compared with BBHC synthesized by conventional heating methods, there was no isomerism phenomenon in their structures.
