<p>Organic tetrasubstituted ester and amide derivatives of pyrophosphoric or hypophosphoric acid are prepared by reacting a tetramethylammonium salt of an appropriately disubstituted derivative of orthophosphoric acid with a halogeno-derivative of an appropriately disubstituted derivative of orthophosphoric or phosphorous acid. The products may be of formula <FORM:0985996/C2/1> or <FORM:0985996/C2/2> where R1, R2, R3 and R4 represent radicals (a) of monohydroxy alcohols that are saturated or unsaturated, unsubstituted or nitrated, and belong to the aliphatic, cycloaliphatic, aromatic and/or heterocyclic series, (b) of substituted or unsubstituted monophenols, and/or (c) of aliphatic amines, aromatic amines, cycloaliphatic amines and/or heterocyclic amines in which the nitrogen is in the heterocyclic ring. Many examples are given. Compounds of the above formulae are claimed per se with the provisos that where the R radicals are all from unsubstituted monohydroxy alcohols or unsubstituted monohydroxy phenols, at least one differs from the other three, that where all four R radicals are derived from amines, they all differ from one another, and that when two R radicals are from unsubstituted alcohols and the other two from alkyl amines, either the pair of alcohol radicals or the alkylamine radicals or both pairs are dissimilar. The reaction may be effected in an inert solvent, preferably one in which the (CH2)4NCl formed is insoluble.</p> |
