Bridging sulfide in platinum and palladium phosphine complexes has been extensively used as a scaffold or template to construct heteropolymetallic complexes and activation of organic halides.[1] In this presentation, we shall highlight its recent uses as a catalyst to promote dehalogenation and organosulfur formation under ambient conditions. We shall describe our latest approach to harness the sulfur nucleophilicity to remove stubborn haloaromatics and transform them to useful organic substrates.
