Streamlining Thionyl Tetrafluoride (SOF) and Pentafluoro-Oxosulfate [OSF] Anions Syntheses.

A one pot room temperature synthesis of thionyl tetrafluoride (SOF) from elemental fluorine (F) and thionyl fluoride (SOF) is reported. The selective decagram scale process (100 mmol) allows a quantitative preparation of SOF with high purity. The solid-state structure has also been elucidated and compared with the reported gas phase one.

Silver(i) Perfluoroalcoholates: Synthesis, Structure, and their Use as Transfer Reagents.

Herein we report a general access to silver(i) perfluoroalcoholates, their structure in the solid state and in solution, and their use as transfer reagents. The silver(i) perfluoroalcoholates are prepared by the reaction of AgF with the corresponding perfluorinated carbonyl compounds in acetonitrile and are stable for a prolonged time at -18 °C. X-ray analysis of single crystals of perfluoroalcoholate species showed that two Ag(i) centers are bridged by the alcoholate ligands.

Trifluoromethyl Fluorosulfonate (CFOSOF) and Trifluoromethoxy Sulfur Pentafluoride (CFOSF) - Two Gaseous Sulfur(VI) Compounds with Insulating Properties.

In this work, we analyzed trifluoromethyl fluorosulfonate (CFOSOF) and trifluoromethoxy sulfur pentafluoride (CFOSF) regarding their potential use as dielectrics by investigating some of their intrinsic and extrinsic properties. Both compounds show a higher breakdown voltage than SF with averaged relative breakdown voltages of 1.3±0.

Catalyst-Free Trifluoromethoxylation of Silyl Enol Ethers and Allyl Silanes with Bis(trifluoromethyl)peroxide.

Radical trifluoromethoxylation is an attractive approach to prepare compounds featuring the important OCF group, however most existing methods have focused on aromatic substrates. Here, we report novel methodologies with alkenyl substrates employing bis(trifluoromethyl)peroxide (BTMP) as a practical and comparatively atom economical trifluoromethoxylating reagent. With silyl enol ether substrates, switching reaction solvent allows for the synthesis of either α-(trifluoromethoxy)ketone products or unprecedented alkenyl-OCF species.

The Tris(pentafluorophenyl)methylium Cation: Isolation and Reactivity.

Herein, we present two different routes for the synthesis of the perfluorinated trityl cation, which allowed the handling of the free, uncoordinated species in organic solvents for the first time. The usage of the weakly coordinating anion [Al(OTeF ) ] and its derivatives allows the characterization of this species by NMR spectroscopy and most importantly by single-crystal X-ray diffraction. The high hydride ion affinity of the cation is shown by hydrogen abstraction from isobutane.
