10.0 g (54 mmol) of commercially available 2,2,5,5-tetramethyl-3,4-(2H, 5H)-furandione hydrazone oxime are heated under reflux for 2 hours with 75 g (1.1 mmol) of hydroxylamine hydrochloride in 800 ml of water. The precipitated product is filtered off with suction and washed with water. 8 g (86%) of 2,2,5,5-tetramethyl-3,4(2H, 5H)-furandione dioxime are obtained as a mixture of 2 isomers, m.p. 252° C.
