Aminophosphines RnP(NR'2)3-n (n = 2, 1, 0; R = Ph, c-Hex, (-)Men, t-Bu; R' = Me, Et, n-Bu) react with 2,4-Bis(aryl)-1,3,2,4-dithiadiphosphetane-2,4-disulfides (ArPS2) (Ar: Ph, 4-Methoxyphenyl = An, Naphthyl, Thienyl) under formal insertion of monomeric (ArPS2)-units in one or in two of the λ3-P-N-bonds to yield chiral organophosphorus compounds Ar(R'2N)P(S)-S-PRn(NR'2)2-n (n = 2, 1, 0) and 2PRn(NR'2)1-n (n = 1, 0).At room temperature chiefly the λ3-P-N and λ3-P-S bonds in these products are solvolyzed by H2O or methanol with formation of mixtures of compounds.With hydrogen chloride An(Et2N)P(S)-S-PPh(NEt2) is converted into An(Et2N)P(S)-S-PPh(Cl).Addition of sulfur yields Ar(R'2N)P(S)-S-P(S)Rn(NR'2)2-n (n = 2, 1).Stereoisomerism of the new compounds is discussed and their structures as well as the composition of reaction mixtures are deduced from 31P-NMR-spectra.
