Abstract
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.File in questo prodotto:
