A Tunable Trifluoromethyliodonium Reagent

Angewandte Chemie International Edition, 2019
AbstractFour complexes of MCl4 (M=Ti, Zr, Hf) with the hypervalent trifluoromethyl iodine reagent trifluoromethyl‐1,3‐dihydro‐3,3‐dimethyl‐1,2‐benziodoxole (1,=L) are described. With TiCl4, an I−O bond cleavage occurs, leading to the formation of the trifluoromethyliodonium alcoholate complexes [Ti2Cl6(L)4]Cl2 (2 a) and Ti2Cl8(L) (2 b).

Reagent-in-film (RIF): A simplified reagent delivery system

Analytical Biochemistry, 1979
Abstract Water-soluble or dispersible reagents, including antigens, antibodies, enzymes, substrates, stains, antibioties, or nutrient media, can be incorporated into supported or unsupported hydrocolloid films, dried, and stored in this form until ready for use.

Copper-Catalyzed Difluoromethylation of Aryl Iodides with (Difluoromethyl)zinc Reagent.

Organic Letters, 2016
The combination of difluoroiodomethane and zinc dust or diethylzinc can readily lead to (difluoromethyl)zinc reagents. Therefore, the first copper-catalyzed difluoromethylation of aryl iodides with the zinc reagents is accomplished to afford the ...
