ABSTRACT:
Carbamoyl chlorides derived from secondary aliphatic amines having alkyl groups which are branched in the 1-position are prepared by passing phosgene at an elevated temperature into the corresponding, initially taken--if appropriate dissolved in an inert solvent--secondary aliphatic amines having alkyl groups which are branched in the 1-position.
The reaction products are intermediates in various specialized fields, particularly in the plant protection sector.
