反応手順
Two moles of phthalic anhydride (296 g) and one mole of oxalic dihydrazide (118 g) in xylene (2.5 l) were heated at reflux until two moles of water were removed (about 24 hours). The product was filtered and dried at 50° C. N,N'-bis(phthalimido)oxamide was obtained in 94-6 percent yield. The compound was a white solid melting at 295° C. (dec.) and having the following elemental analysis by weight percent:
