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

Abstract

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.

Photoredox Catalytic α‐Alkoxypentafluorosulfanylation of α‐Methyl‐ and α‐Phenylstyrene Using SF6

“…However, formation of the C−S bond still requires the use of extraordinarily toxic reagents, like S 2 F 10 , and the mixed‐sulfur halogenides SF 5 Cl and SF 5 Br. In contrast, reports on non‐toxic SF 6 in synthesis are rare although this would have strong environmental advantages . SF 6 is still indispensable as an insulating gas in technical applications, like high‐voltage gears, and as a protecting gas in the production of metals.…”

The Versatile Behavior of Platinum Alkyne Complexes towards XeF2: Formation of Fluorovinyl and Fluorido Complexes

“…[11][12][13][14][15][16][17][18][19] One approach to access fluorinated buildingb locks involves metal-mediated fluorination reactions, which can often be regarded as efficient alternatives to conventional fluorination methods. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] The CÀFb ond formation generally takes place either by electrophilic or nucleophilic fluorinationo ft he ligand or the metal. For the latter,m etal fluorido species can be intermediates, which then, for instance, undergo CÀFr eductive elimination.…”

“…Im Gegensatz dazu sind Berichte über das ungiftige SF 6 in der Synthese rar, obwohl es große Vorteile für die Umwelt brächte . SF 6 ist als Isolierungsgas in technischen Anwendungen, wie der Hochchspannungstechnik, und als Schutzgas in der Metallproduktion noch unverzichtbar.…”
