Abstract

Two borate salts, dimethylammonium bis [3-isopropylbenzene-1, 2-diolato (2−)-O, O′] borate and dimethylammonium 3, 3′′-ethylenebis (3′-methylbiphenyl-2, 2′-diolato (2−)- O, O′) borate, were synthesised from the corresponding catechol and tetraphenol respectively. The configurational stability of these salts was determined by variable temperature 1H NMR spectroscopy; the activation energies for the racemisation process ...
