2,2-dichloro-N,N-bis(prop-2-enyl)acetamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Twenty and eight-tenths grams of N,N-diallyl dichloroacetamide was mixed with 25 g. of diethylene glycol dimethyl ether (diglyme), 1 g. of ferrous chloride (FeC12 ·4H2 0) added and the mixture was heated at reflux for 30 minutes. The conversion was monitored by the appearance of a new carbonyl peak at ~ 5.8 microns in the infrared. An additional gram of ferrous chloride (FeC12 ·4H2 0) was added and heating was continued for an additional 30 minutes. The reaction mixture was diluted with methylene chloride, washed with water and dried and stripped. The dark liquid product was distilled under vacuum to give 8.4 g. of light yellow oil, b.p. 124°-127° C. at 0.25 mm. nD30 1.4850. the mixture was heated at reflux for 30 minutes heating washed with water dried The dark liquid product was distilled under vacuum to give 8.4 g
