Procedure

260 ml of oxalyl chloride were added to 225 g of trichloroacrylamide in 525 ml of dichloroethane cooled to 2° C and the mixture was held at 0° C for 1 hour and then refluxed for 16 hours. The resulting solution was evaporated under reduced pressure and the residue was distilled to obtain 232 g of trichloroacryloyl-isocyanate boiling at 86° C under 20 mm Hg and having a refractive index nD23 = 1.538.
