Activation of SF6 at Platinum Complexes: Formation of SF3 Derivatives and Their Application in Deoxyfluorination Reactions

Abstract The activation of SF 6 at [Pt(PR 3 ) 2 ] R=Cy, i Pr complexes in the presence of PR 3 led selectively and in an unprecedented reaction route to the generation of the SF 3 complexes trans ‐[Pt(F)(SF 3 )(PR 3 ) 2 ]. These can also be synthesized from SF 4 and the SF 2 derivative trans ‐[Pt(F)(SF 2 )(PCy 3 ) 2 ][BF 4 ] was characterized by X‐ray crystallography. trans ‐[Pt(F)(SF 3 )(PR 3 ) 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 SF 6 as fluorinating agent.
