超声辐射下,于二氯甲烷溶剂中,以锌粉或铝粉还原四氯化钛的四氢呋喃配合 物可生成相应的低价钛配合物,室温下此配合物可使一些芳香醛在4~25 min内还 原偶联为相应的邻二醇,收率为33%~98%.

关键词: 钛络合物, 还原, 偶联, 二氯甲烷, 芳香族醛,

Complexes of titanium tetrachloride and tetrahydrofuran in CHaC^ can be reduced by Zn or Al to the corresponding low valent titanium complexes, which can reduce some aromatic aldehydes to the corresponding pinacols in 33 % ~ 98 % yields at room temprature within 4 ~ 25 min.

Key words: TITANIUM COMPLEX;REDUCTION;COUPLED;DICHLOROMETHANE;aromatic aldehyde, ALCOHOL
