✦ Synopsis

Both carboxyl groups in the title molecule, C 9 H 12 O 4 , have gauche orientations [relative to the (HOOCÐ)CÐC(Ð COOH) bond] and participate in hydrogen bonds, linking the molecules into an in®nite chain.

Experimental

Hydrogen was introduced to a stirred mixture of (II) (0.65 g, 4 mmol), palladium on carbon (5% Pd, 100 mg) and acetic acid (10 ml). The catalyst was ®ltered off and the solvent removed using a rotary evaporator. The product was recrystallized from doubly distilled water, giving colourless crystalline (I) in 88% yield (0.58 g,
