Abstract
A process for producing a compound containing an acylated nitrogen atom in which the adduct compound formed from an N-protonated cation and a chloride, bromide or iodide anion or the free nitrogen base is reacted with an acyl halide, preferably an acyl chloride, in the presence of an acid that drives off the released hydrogen chloride (HCl), hydrogen bromide (HBr) or hydrogen iodide (HI).
Claims7
A process for producing a compound with an acylated nitrogen atom, said process comprising reacting an acyl halide with a nitrogen compound to form the corresponding N-acylated compound and a hydrogen halide;
- wherein:
- acyl represents an RC(O) group in which R represents a linear or branched alkyl with 1 to 6 carbon atoms, phenyl, linear or branched alkyl with 1 to 6 carbon atoms which is substituted with at least one halogen atom, or phenyl which is substituted at least one halogen atom;
- said nitrogen compound is present in the form of its free base or is N-protonated and present in the form of a salt with a chloride, bromide or iodine anion;
- and
- the reaction is carried out in the presence of an acid of sufficient strength to expel the hydrogen halide from the reaction mixture.
