reported. By taking advantage of the in situ generated α-CF3-benzylsilver intermediates derivedfrom the nucleophilic addition of silver fluoride to gem-difluoroalkenes, this strategy bypasses the use of a strong base, thus enabling a mild and general synthetic method for ready access to non-symmetric α,α-disubstituted trifluoroethane derivatives.

An azole derivative of formula (I) having a fluorovinyl moiety or a pharmaceutically acceptable salt thereof is superior to the conventional antifungal drugs in antifungal activity against a wide spectrum of pathogenic fungi, and has advantageously low toxicity.

A photochemicalapproach for the preparation of α-keto-N-acyl sulfoximines from NH sulfoximines and gem-difluoroalkenes has been developed. In the presence of NBS, the reactions proceed in air without the need of a photocatalyst or additional oxidant. Results of mechanistic studies suggest that the two oxygens in the products stem from water and dioxygen.

Design and Synthesis of TY‐Phos and Application in Palladium‐Catalyzed Enantioselective Fluoroarylation of
<i>gem</i>
‐Difluoroalkenes
highly enantioselectivefluoroarylation of gem‐difluoroalkenes with aryl halides is presented by using a new chiral sulfinamide phosphine (Sadphos) type ligand TY‐Phos. N‐Me‐TY‐Phos can be easily synthesized on a gram scale from readily available starting materials in three steps. Salient features of this work including readily available starting materials, good yields, high enantioselectivities as well
