GOLD(I) COMPLEXES WITH BIOLOGICALLY ACTIVE THIOLATE LIGANDS

摘要

The reaction of ethanolic solutions of Na(SR) (SR=4-oxo-2-thioxopyrimidines) with [AuCIL] (L=PPh3, PPh2Me and AsPh3) gives [Au(SR)L]; when PPN[AuCl2] or NBu4[AuBr(C6F5)] are used instead, PPN[Au(SR)(2)] and NBu4[Au(C6F5)(SR)] are obtained. The structure of [Au(SR1)(PPh3)] has been established by X-ray diffraction, and shows a linear coordination at gold involving the phosphine phosphorus and the exocyclic sulfur atom of the organic ligand.
