hydroxylamine-O-sulfonic acid → HCID 19774688, compound

Participants

Reaction Steps

30.7 g (0.16 mol) of 5-formyl-2-propionylcyclohexane-1,3-dione were introduced into 150 ml of distilled water and, at room temperature, 21.0 g (0.19 mol) of hydroxylamine-O-sulfonic acid were added. The mixture was then stirred at room temperature overnight. The precipitate was filtered off with suction, washed with water and dried. 23.8 g (71% of theory) of 3,5-dioxo-4-propionylcyclohexanecarbonitrile were obtained (melting point 70° to 74° C).
