一系列芳香醛在Al-TiCl3-CH2Cl2体系中反应12 h, 以20%~70%的产率得1,2-二醇产品, 相同体系中微波辐射8 min相应1,2-二醇的产率达65%~94%. 微波辐射下合成1,2-二醇的优点是时间短、产率高、操作简单.

The coupling reactions of aromatic aldehydes were carried out in 20%~70% yields using Al-TiCl3-CH2Cl2 system with stirring for 12 h. The reactions in the same system gave 1,2-diols in 65%~94% yields under microwave irradiation for 8 min. The main advantages of the present procedure are a short-period of time, higher yields and operational simplicity un-der microwave irradiation.
