Abstract

A series of mixed ligand Au^I 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 Au^I 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 Au^I.
