Procedure

The procedure was the same as described above for bis(tetrabutylammonium) terephthalate using 0.277 g (1.67×10-3 mol) of terephthalic acid and benzyltrimethylammonium hydroxide (3.4 mL, 0.57 g, 3.6×10-3 mol) (40% by weight in methanol). The yield of salt obtained after removal of solvent was 0.688 g, 88%. 1H and 13C NMR spectra (FIGS. 47 and 48) of the salt in D2O were obtained and are in accord with the expected structure.
