Versuchsvorschrift

Mix methallyl acetate (228 g, 2.0 mol) and benzene (1 L) and cool to 5° C. Add aluminum chloride (266 g, 2.0 mol) over approximately 30 minutes while maintaining the temperature below 10° C. Add, in portions of 50 mL to 80 mL each, to a 5° C. mixture of aluminum chloride (15 g) in benzene (600 mL). After addition is complete, stir at 0-3° C. for ½ hour, pour onto ice (2 kg) and separate the organic layer. Wash with water (2×300 mL), dry (Na2SO4), and distill to give neophyl acetate.
