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 کاملElectrophilic fluorination using a hypervalent iodine reagent derived from fluoride.
The air and moisture stable fluoroiodane 8, readily prepared on a 6 g scale by nucleophilic fluorination of the hydroxyiodane 7 with TREAT-HF, has been used as an electrophilic fluorinating reagent for the first time to monofluorinate 1,3-ketoesters and difluorinate 1,3-diketones in good isolated yields.

In the title compound, C(7)H(12)N(2)O(2)S(2), the conformation of the dithia-cyclo-pentane ring is a half-chair, with a total puckering amplitude Q(T) = 0.473 (5) Å. Inter-molecular C-H⋯N and C-H⋯O inter-actions help to establish the packing.

In the crystal structure of the title salt, C2H8NO(+)·I(-), N-H⋯O, N-H⋯I and O-H⋯I hydrogen bonds lead to the formation of layers staggered along the c axis.
متن کامل(2-Aminophenyl)methyldiphenylphosphonium iodide
The asymmetric unit of the title compound, C(19)H(19)NP(+)·I(-), contains two tetra-alkyl-phospho-nium cations and two I(-) anions. The P atoms are four-coordinated in distorted tetra-hedral configurations by three phenyl and one methyl C atoms. There are weak intra- and inter-molecular N-H⋯I contacts.
