Copper(I) complexes of N-thioacylamido(thio)phosphates and triphenylphosphine

Heteroligand copper(I) complexes of bi- or bis-bidentate acylamidophosphates PhC(S)NHP(S)(OPr-i)2, PhC(S)NHP(O)(OPr-i)2, Et2NC(S)NHP(S)(OPr-i)2, PhNHC(S)NHP(S)(OPr-i)2, N-(4-aminobenzo-15-crown-5)-C(S)NHP(S)(OPr-i)2, N,N-(1,10-diaza-18-crown-6)-[C(S)NHP(S)(OPr-i)2]2, and triphenylphosphine were prepared and characterised. Copper is bound by two PPh3 and one SCNPX (X = O, S) fragment of chelating ligand in all cases. Triphenylphosphine molecules reversibly dissociate in solution. Details of the X-ray structures of (Ph3P)2Cu[PhC(S)NP(S)(OPr-i)2] and (Ph3P)2Cu[Et2NC(S)NP(S)(OPr-i)2] are reported.

N-thioacylamidophosphates RC(S)NHP(X)(OPr-i)2 = HL (R = Ph, NHAr or NAlk2; X = O, S) form copper(I) triphenylphosphine complexes (Ph3P)2Cu[RC(S)NP(X)(OPr-i)2-S,X]. Copper atom coordinated by two donor atoms of chelating ligand and two PPh3 molecules in all complexes.Figure optionsDownload as PowerPoint slide
