水溶液中金属镓作用下频哪醇合成的研究

Study on the Synthesis of Pinacol Using Gallium in Aqueous Media

超声波引发或搅拌下Ga-H2O-CH3OH体系中进行了一系列芳香醛的偶联反应，室温下分别反应2h或4h得69％～82％或31％～76％的频哪醇产品．该方法操作简便、速度快、产率高．

The reduction coupling reactions of aromatic aldehydes were carried out in 69 % --82 % （or 31% --76 %） yield with Ga-H2O-CH3OH at room time for 2 h （or 4 h） under ultrasound irradiation （or stirring）. The experimental results showed that the proper ultrasound irradiation could speed up the coupling reaction and obtain high yield with simple operation.
