WebMentioning: 6 - Ynamides consisting of an electron-withdrawing group on the nitrogen atom have proven to be powerful and versatile building blocks that are involved in a variety of useful chemical transformations. Nonetheless, their utilization in asymmetric catalysis is still in its infancy and has only recently attracted the attention of the synthetic organic … 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 …
