Triscarboxylic acids, when treated with hydroxylamines in the presence of water-soluble carbodiimide in THF-H2O, at pH≈4.8, yield the corresponding trishydroxamic acids in good yields.
The formation of trithiametacyclophanes from the trisodium salt of a tris(mercaptoalkyl)benzene and a trisbromoalkylmethane is described. 1H N.m.r. spectra were used to determine the structures of the products, with the aid of shiftreagents.
