Versuchsvorschrift
A solution of acetonitrile oxide was prepared by passing chlorine (10.8 grams) over 30 minutes into a stirred suspension of acetaldoxime (9 grams) and sodium bicarbonate (25.2 grams) in water at 0° C was added 2,3-dichlorobenzoquinone (17.7 grams) portionwise over 15 minutes. The mixture was stirred at 0°-5° C for 2 hours and then extracted with methylene chloride. The dried extracts were evaporated to dryness under reduced pressure and the residue recrystallized from ethanol to give the desired product as yellow crystals having a melting point of 214°-215° C.
