A novel series of O,O′,O″,O?- tetraaryldithioimidophonates [(ArO)2PS]2NH 4 were synthesized by the reaction of O,O,-diaryl phosphorochlorothionates 2 and diarylphosphonothioic amide under a strong basic condition. The key intermediat

Unsymmetrical bidentate ligands R2P(E)-N(H)-P(E′)R′2 [R, R′ = Ph, OPh, iPr; E, E′ = O, S, Se] have been synthesised using the condensation reaction of an amino compound, R2P(E)NH2 [R = PhO, Ph; E = O, S, Se], with a phosphorus electrophile, R′2P(E′)C1 [R′ = iPr, Ph, OPh; E′ = O, S, Se]. Deprotonated ligands (with KOtBu) can be treated with Pd(OAc)2 to give [Ph2P(S)-N-P(O)(OPh)2]2Pd, [iPr2P(S)-N-P(O)(OPh)2]2Pd and [Ph2P(S)-N-P(S)(OPh)2]2Pd, which show either four-membered or six-membered chelate rings. The new compounds were studied spectroscopically (NMR, IR and Raman) and by X-ray crystallography.
