Question

Trichloroacetyl chloride reaction with acrylonitrile

Answer 1

The synthesis of 3,5,6-trichloropyridin-2-ol via the CuCl-catalyzed reaction of trichloroacetyl chloride and acrylonitrile under both pressure and atmospheric conditions and the hydrolysis of the reaction mixture were reinvestigated. The products and byproducts formed in each case, before the hydrolysis step, were characterized, and the factors causing their formation are discussed. It was found that two newly identified byproducts influence the yield of the reaction
