Abstract

A number of mixed ligand complexes of gold(I) with various selenones and Ph3P, [Ph3PAuSe=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 gold(I) binding viaa selenone group. An upfield shift in the 13 C-n.m.r. for the C=Se resonance of selenones and downfield shifts in 31P-n.m.r. for the Ph3P moiety are consistent with the selenium coordination to gold(I). Available data in the literature suggest that P–Au–Se type complexes are usually linear.
