A process for preparing a difluoro chelato borate salt comprising an anion A of formula (I) wherein (I)' is a bidentate radical derived from a 1,2-, 1,3- or 1,4-diol, from a 1,2-, 1,3- or 1,4- dicarboxylic acid or from a 1,2-, 1,3- or 1,4-hydroxycarboxylic acid by abstracting the two H atoms of pairs of adjacent OH groups of the respective diol, hydroxycarboxylic acid or dicarboxylic acid; comprising step (i) reacting (a) one or more BF3 sources; (b) a dihydric compound selected from 1,2-, 1,3- and 1,4-diols, 1,2-, 1,3- and 1,4-dicarboxylic acids, and 1,2-, 1,3- and 1,4-hydroxycarboxylic acids; (c) one or more second boron sources which do not contain F; and (d) one or more proton acceptors.
制备二氟螯合硼酸盐的过程包括具有式(I)的阴离子A,其中(I)'是从1,2-、1,3-或1,4-二醇、1,2-、1,3-或1,4-二羧酸或1,2-、1,3-或1,4-羟基羧酸中提取得到的双齿基团,通过提取相应二醇、羟基羧酸或二羧酸的相邻羟基对的两个H原子;包括步骤(i)反应(a)一种或多种BF3源;(b)从1,2-、1,3-和1,4-二醇、1,2-、1,3-和1,4-二羧酸以及1,2-、1,3-和1,4-羟基羧酸中选择的二元化合物;(c)一种或多种不含F的第二硼源;和(d)一种或多种质子受体。
