The reaction between ethanedioyl (oxalyl) dihalides and Ag2C2O4: A route to Staudinger's elusive ethanedioic (oxalic) acid anhydride

Ethanedioic (oxalic) acid anhydride 1 was prepared for the first time and its dimeric cyclic nature established by spectroscopic and chemical evidence. The strong instability of 2-chloro-2-oxoethanoic acid 3 was incidentally observed. The chemical behaviour of 1 with MeOH and CH2N2 was investigated.
