Activation of SF at Platinum Complexes: Formation of SF Derivatives and Their Application in Deoxyfluorination Reactions.

The activation of SF at [Pt(PR ) ] R=Cy, iPr complexes in the presence of PR led selectively and in an unprecedented reaction route to the generation of the SF complexes trans-[Pt(F)(SF )(PR ) ]. These can also be synthesized from SF and the SF derivative trans-[Pt(F)(SF )(PCy ) ][BF ] was characterized by X-ray crystallography. trans-[Pt(F)(SF )(PR ) ] complexes are useful tools for deoxyfluorination reactions and novel fluorido complexes bearing a SOF ligand are formed. Based on these studies a process for the deoxyfluorination of ketones was developed with SF as fluorinating agent.
