direct reduction of aliphatic carboxylic acids with a variety of functional groups to a primary alcohol using the mild reducing reagent tetramethyldisiloxane (TMDS), in the presence of a catalytic amount of InBr3 has been developed. This simple reducing system, when used together with a hydrosilane, allows the preparation of the diphenylmethane derivative directly from an aromatic carboxylic acid and
在催化量的 InBr3 存在下,使用温和的还原剂四甲基二硅氧烷 (TMDS) 将具有多种官能团的脂肪族羧酸直接还原为伯醇的简单实用方法已被开发出来。这种简单的还原系统,当与氢硅烷一起使用时,可以直接从芳族羧酸和芳族化合物制备二苯甲烷衍生物。
