Phicf3cl
WebPhICF3Cl was an effective CF3source for the transformation. As a result, a generic platform is established to divergently synthesize N-trifluoromethylated tetrazoles, imidazoles, and 1,2,3-triazoles by using sodium azide, activated methylene isocyanides, and diazo compounds as dipoles. WebFeb 28, 2024 · The use of PhICF 3 Cl as a powerful trifluoromethylating agent allows easy transformations. A set of trifluoroethylated carbocycles and aza-hereocycles were efficiently synthesized in good yield and selectivity. A broad substrate scope, mild reaction conditions, and easy operation would make this method well-suited for applications.

WebWe described a trifluoromethylation of alkenes using PhICF3Cl as bifunctional reagent. Chlorotrifluoromethylated products were obtained when nonconjugated alkenes were treated with PhICF3Cl in 1,4-dioxane at 60 °C, while vinyl C–H trifluoromethylated products were obtained by further elimination of hydrochloride in the case of those conjugated … WebMay 8, 2024 · Catalyst-free and selective trifluoromethylative cyclization of acryloanilides using PhICF 3 Cl Catalyst-free and selective trifluoromethylative cyclization of acryloanilides using PhICF 3 Cl Org Biomol Chem. doi: 10.1039/c9ob00601j.

WebThis work describes a catalyst-free protocol to innately produce electrophilic CF3 species from PhICF3Cl for trifluoromethylative cyclization of acryloanilides. Trifluoromethylation-triggered cyclization of alkenes provides a useful route to CF3-containing cyclic compounds. Current approaches to generate CF3-based initiators from a CF3 source require a catalyst … WebPhICF3Cl was an effective CF3 source for the transformation. As a result, a generic platform has been established for the first time to divergently synthesize N -trifluoromethylated tetrazoles, imidazoles, and 1,2,3-triazoles by using sodium azide, activated methylene isocyanides, and diazo compounds as dipoles, respectively.
