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

PHOSPHORORGANISCHE VERBINDUNGEN 90 Methodische Ausgestaltung der P-C und P-S-Cyanolyse am Beispiel einiger Heterophosphoniumsalze

Treatment of allylamido-phosphonium salts with dry tetrabutylammonium cyanide in methylenechloride delivers after removal of the allyl group phosphinous acid amides with retention of configuration (P-C-cyanolysis).Allyl-O-alkylphosphonium salts undergo the Arbosov reaction under the above conditions, while allyl-S-alkyl phosphonium salts undergo fission of the P-S bond (P-S cyanolysis).Equally good results were obtained using KCN in methylene chloride accompained by catalytic amounts of 18-crown-6 ether; thus optically active benzyl-methyl-phenyl-phosphine-sulfid gave the corresponding phosphine with retention of configuration.Dithiophosphinic acid esters and thiophosphinic acid amides, after conversion to the corresponding quasiphosphonium salts via S-alkylation and subsequent treatment with tetrabutylammonium cyanide in methylenechloride, also give the corresponding thiophosphinous acid ester and phosphinous acid amide respectively.Thiophosphinic acid O-alkyl esters (R2P(S)OR') give however the thiophosphinic S-alkyl ester (R2P(O)SR') via an Arbusov reaction.The P-C cyanolysis of allyl-triphenylphosphoniumbromide using KCN/18-crown-6 or tetrabutylammonium cyanide in aprotic medium stops at the stage of the intermediary red-coloured ylide; addition of a proton-donor then results in the subsequent rearrangement to the corresponding propenyl-phosphonium salt.
