Chemical properties of N'-cyanodiazene N-oxides. Reactions involving the nitrile group
摘要:
The reactivity of the nitrile group in N'-cyanodiazene N-oxides has been examined for the first time. A general approach to the synthesis of nitrogenous functional derivatives of azoxycarboxylic acids by reaction of N'-cyanodiazene N-oxides with nucleophiles (water, alcohol, and hydroxylamine) is described. A method of synthesis of novel azoxy-1,2,4-oxadiazoles and tetrazoles has been developed in which aliphatic, aromatic, or heterocyclic N'-cyanodiazene N-oxides are reacted with benzonitrile N-oxide or sodium azide. Trimerization of N-cyanodiazene N-oxides, catalyzed by anhydrous HCl, has given novel symm-triazines in which the heterocycle bears three diazene N-oxide groups.

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.
