Hydrochloric Acid → 3-Chloro-3-methyl-2-nitroso-1-butyl acetate

Participants

Reaction Steps

3,3-Dimethylallyl acetate (25 ml.), iso-amyl nitrite (45 ml.) and glacial acetic acid (65 ml.) were cooled in an ice-salt mixture. An ice-cold mixture of concentrated hydrochloric acid (20 ml.) and glacial acetic acid (20 ml.) was added gradually with stirring. The solution became green and towards the end of the addition a white solid precipitated. The solid was collected by filtration and dried (13 g.) Recrystallisation from CCl4 -- 40°/60° petrol gave the title compound as colourless needles (10 g.) m.p. 117°-119°.
