Copper-catalyzed trifluoromethylation of alkenes with an electrophilic trifluoromethylating reagent
An efficient method for the copper-catalyzed trifluoromethylation of terminal alkenes with an electrophilic trifluoromethylating reagent has been developed. The reactions proceeded smoothly to give trifluoromethylated alkenes in good to excellent yields. The results provided a versatile approach for the construction of Cvinyl-CF3 bonds without using prefunctionalized substrates.
متن کاملCopper-catalyzed trifluoromethylation of alkenes: synthesis of trifluoromethylated benzoxazines.
A simple base and ligand free copper catalyzed method for the construction of trifluoromethylated benzoxazines has been developed by using Umemoto's reagent. It involves the oxidative difunctionalization of alkenes through tandem C-O and C-CF3 bond formations. Furthermore, synthesized benzoxazines were selectively converted into trifluoromethylated allylic and (E)-vinylic benzamides by the trea...
متن کامل1-Trifluoromethylated isoquinolines via radical trifluoromethylation of isonitriles.
A simple and efficient approach to biologically important 1-trifluoromethylated isoquinolines starting with readily prepared β-aryl-α-isocyano-acrylates and the commercially available Togni reagent as the CF3 radical precursor is described. These transformations occur in the absence of any transition metals and the title compounds are obtained in moderate to excellent yields. This protocol comp...
متن کاملIntroducing a new radical trifluoromethylation reagent.
Perfluoro-3-ethyl-2,4-dimethyl-3-pentyl radical (PPFR) is a persistent radical stable at room temperature, but easily decomposes at 90 °C to produce a CF3 radical which is able to react with a variety of aromatic compounds to afford the corresponding trifluoromethyl derivatives, usually as mixtures of regioisomers in good to excellent overall yields.

تعارفات کنش های گفتاری هستند که افراد در زندگی روزمر? خود به منظور برقراری دوستی یا تداوم روابط مسالمت آمیز به کار می برند. ساز و کار تعارف مختص زبان انگلیسی یا هر زبان دیگری نیست و پدیده ای است جهانی و در همه زبانها حضور دارد. تفاوتی که از این نظر در زبانها و فرهنگ ها وجود دارد مربوط به پاسخ به این کنش گفتاری در گفتمان است. این مطالعه به بررسی تنوع پاسخ های انگلیسی و عربی به کنش گفتاری تعارف د...
