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

N-thioacylamidophosphates RC(S)NHP(X)(OPr-i) 2 = HL (R = Ph, NHAr or NAlk 2; X = O, S) form copper(I) triphenylphosphine complexes (Ph 3P) 2Cu[RC(S)NP(X)(OPr-i) 2- S, X].

Description
Summary:N-thioacylamidophosphates RC(S)NHP(X)(OPr-i) 2 = HL (R = Ph, NHAr or NAlk 2; X = O, S) form copper(I) triphenylphosphine complexes (Ph 3P) 2Cu[RC(S)NP(X)(OPr-i) 2- S, X]. Copper atom coordinated by two donor atoms of chelating ligand and two PPh 3 molecules in all complexes. Heteroligand copper(I) complexes of bi- or bis-bidentate acylamidophosphates PhC(S)NHP(S)(OPr-i) 2, PhC(S)NHP(O)(OPr-i) 2, Et 2NC(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 PPh 3 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 (Ph 3P) 2Cu[PhC(S)NP(S)(OPr-i) 2] and (Ph 3P) 2Cu[Et 2NC(S)NP(S)(OPr-i) 2] are reported.
