Enones from Acid Fluorides and Vinyl Triflates by Reductive Nickel Catalysis.
Organic Letters, 2019A nickel-catalyzed reductive coupling between acid fluorides and vinyl triflates has been described. This method provides an efficient access to various enones and avoids the requirement for acyl or vinyl metallic reagents in the conventional approaches.

Catalytic C-H/C-F Coupling of Azoles and Acyl Fluorides.
Chemistry, 2019A method for the palladium/copper-catalyzed direct acylation of azoles with acyl fluorides is described. This study reports the first examples of acyl fluorides being used as acylation reagents in transition-metal-catalyzed aromatic C-H bond ...

Palladium-Catalyzed Reductive Conversion of Acyl Fluorides via Ligand-Controlled Decarbonylation.
Organic Letters, 2018Ligand-controlled non-decarbonylative and decarbonylative conversions of acyl fluorides were developed using a Pd(OAc)2/Et3SiH combination. When tricyclohexylphosphine (PCy3) was used as the ligand, aldehydes were obtained as simple reductive conversion ...

A new reductive dl-mandelic acid loading approach for moisture-stable Mn4+ doped fluorides.
Chemical Communications, 2018In this communication, a novel reductive dl-mandelic acid loading approach for moisture-stable Mn4+ doped fluorides is reported. After loading dl-mandelic acid, the characteristic luminescence properties of the treated Mn4+ doped potassium ...

Tetramethylphosphonium Fluoride: “Naked” Fluoride and Phosphorane
Inorganic Chemistry, 2003Me(4)PF was investigated in the solid state, in the gas phase, and in solutions. Vibrational spectra of the solid and a single-crystal structure show an ionic tetramethylphosphonium fluoride. The compound crystallizes in the space group Pbca with a = 1016.0(1), b = 1018.0(1), c = 1205.8(4) pm, and Z = 8.
