摘要：
A series of mixed ligand AuI complexes with selenourea (Seu) and various phosphines, [R3PAuSeu]Cl, have been prepared and characterized by elemental analysis, i.r. and n.m.r. methods. A decrease in the i.r. frequency of the C=Se mode of Seu upon complexation is indicative of AuI binding via a selenone group. An upfield shift in the 13C-n.m.r. for the C=Se resonance of Seu, and downfield shifts in 31P-n.m.r., for the R3P moiety are consistent with selenium coordination to AuI.
