Abstract: Disclosed is a method for producing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphite diamides, aminophosphines, diaminophosphines, phosphite amide halogenides, and aminophosphine halogenides by separating an acid in the presence of an auxiliary base. Said auxiliary base b) forms a salt with an acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation of the liquid salt, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible phases in a suitable solvent.

Abstract: Disclosed is a method for separating acids from chemical reaction mixtures by means of an auxiliary base. Said auxiliary base b) forms a salt with the acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible fluid phases in a suitable solvent.
