, p. 190 - 193 (2003)
A procedure was developed for preparation of bisamides of cyclic ortho-dicarboxylic acids by acylation of m- or p-phenylenediamine in acetone solution at room temperature simultaneously with two different anhydrides of cyclic or aromatic ortho-dicarboxylic acids; another process consisted in treating an anhydride of aromatic or cyclic dicarboxylic acid with monoamide of cis-4-cyclohexene-1,2-dicarboxylic acid in dimethylformamide at room temperature.
