Abstract

Mixed ligand complexes of gold(I) with various selenones and Me ₃P, [Me₃PAuSe=C < ]Cl, have been prepared and characterized by elemental analyses, i.r. and n.m.r. methods. A decrease in the i.r. frequency of the > C=Se mode of selenones upon complexation is indicative of selenone binding to gold(I) via a selenone group. An upfield shift in ¹³C-n.m.r. for the > C=Se resonance of selenones and downfield shifts in ³¹P-n.m.r. for Me₃P moiety are consistent with the selenium coordination to gold(I). The steric effect as well as the basicity of Me₃PAu⁺ plays a significant role in bonding with Se-containing ligands compared to the Et₃PAu⁺ and Ph ₃PAu⁺ complexes.
