This invention provides a process for preparing amide derivatives of acids by the reaction of haloaminotriazines and acid halides. This invention also provides a process for preparing isocyanates and isocyanate adducts from amide derivatives derived from haloaminotriazines and acid halides such as oxalyl chloride, phosgene and phosgene analogs. Melamine derived acid amides are prepared by reaction of trichloro and hexachloromelamines with chloroformates and acid chlorides. The by-product chlorine may be recycled in this process. Amides, carbamates, sulfonamides, phosphoramides, and related amide derivatives may be prepared by the novel processes of the invention.
