ABSTRACT:
.alpha.-haloalkylcarbamyl halides are manufactured by reacting N-tert.-alkyl-N-1-alkenyl-carbamyl halides with a hydrogen halide at from -78.degree. C. to +80.degree. C.
The .alpha.-haloalkylcarbamyl halides, e.g. .alpha.-chloroalkylcarbamyl chlorides, especially .alpha.-chloroethylcarbamyl chloride, prepared by the process of the invention, are valuable starting materials for the manufacture of surface-coating raw materials, textile coatings, dyes, drugs and crop protection agents.
