Activation of SF6at Platinum Complexes: Formation of SF3Derivatives and Their Application in Deoxyfluorination Reactions.
The activation of SF6at [Pt(PR3)2] R=Cy, iPr complexes in the presence of PR3led selectively and in an unprecedented reaction route to the generation of the SF3complexes trans-[Pt(F)(SF3)(PR3)2]. These can also be synthesized from SF4and the SF2derivative trans-[Pt(F)(SF2)(PCy3)2][BF4] was characterized by X-ray crystallography. trans-[Pt(F)(SF3)(PR3)2] 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 SF6as fluorinating agent.
