Dialkylamino-phenyldi- and -triphosphides from the Degradation of (PhP)5 by Alkali Amides

(PhP)5 and lithium dialkylamides in tetrahydrofuran form equilibrium mixtures of lithium aminophenylphosphides (PhP)nNR2(-) with n = 3 and (mainly) 2.The monophosphides (n = 1) are not formed; it is concluded that they are generally unstable, decomposing to aminodiphosphides and cyclophosphines.Alkylation of an equilibrium mixture gives 1-alkyl-2-dialkylamino-diphenyldiphosphines which, however, are thermally unstable. (PhP)5 degradation equilibria using different anionic nucleophiles are compared. - Key words: Cyclophosphines, Nucleophilic Degradation Equilibria, Aminophosphides, Diphosphines, 13C NMR Spectra

Optically active ethyl-phenyl-phosphinous acid diethylamide 1 was treated with HCl, HBF4, alcohols, thiols, carboxylic acids, esters, anhydrides, acid chloride, compounds with the structure element P-Cl and secondary phosphines to give in each case a racemic mixture of the corresponding, previously described, reaction products.Reaction of optically active 1 with para-cresol, para-cresyltrifluoro-acetate or 2,2,2-trifluoro-ethyl-trifluoro-acetate gives the corresponding optically active ester of ethyl phenyl phosphinous acid under retention of configuration.
