Abstract

Titrations of gold (1) complexes [(AuCI),(PP)] with ligand (PP) were studied by'IP NMR for the bidentate tertiary phosphine ligands Ph2P (CH2) $ Ph2, where n= 1 (dppm), 2 (dppe), 3 (dppp), and 4 (dppb), cis-Ph2PCH= CHPPh2 (dppey), Ph2P (CH2), PEt2 (eppe), and Et, P (CH2), PEt2 (depe). Bis-chelated four-coordinate gold (1) phosphine complexes [Au (PP)~]+ containing either five-or six-membered chelate rings (n= 2 or 3) all exhibited exceptionally ...
