Iron-Catalyzed Cross-Coupling of Functionalized Benzylmanganese Halides with Alkenyl Iodides, Bromides, and Triflates

Various substituted benzylic manganese chlorides were prepared by insertion of magnesium turnings in the presence of MnCl2·2LiCl in THF at -5 °C within 2 h. These benzylic manganese reagents underwent smooth cross-couplings with various functionalized alkenyl iodides, bromides, and triflates or iodoacrylates in the presence of 10 mol % FeCl2 at 25 °C for 1-12 h. Mechanistic studies showed that benzylic manganese halides produced, in the presence of FeCl2, a very reactive iron ate complex.

Pd-Catalyzed Difluoromethylation of Vinyl Bromides, Triflates, Tosylates, and Nonaflates

Pd-catalyzed difluoromethylation of di-, tri- or tetra-substituted vinyl bromides, triflates, tosylates and nonaflates under mild conditions is described. The reaction tolerates a wide range of functional groups, such as bromide, chloride, fluoride, ester, amine, nitrile, and protected carbonyl, thus providing a general route for the preparation of difluoromethylated alkenes.

The palladium-catalyzed trifluoromethylation of vinyl sulfonates

A method for the palladium-catalyzed trifluoromethylation of cyclohexenyl sulfonates has been developed. Various cyclohexenyl triflates and nonaflates underwent trifluoromethylation under mild reaction conditions using a catalyst system composed of Pd(dba

Iron-catalyzed cross-coupling between alkenyl and dienyl sulfonates and functionalized arylcopper reagents

Functionalized arylcopper reagents react readily with alkenyl sulfonates in the presence of catalytic amounts of Fe(acac)3, (10 mol%) providing the expected cross-coupling products in good yields. Ester or cyano group are tolerated. This cross-coupling can be performed with dienyl sulfonates leading to the corresponding substituted dienes. Georg Thieme Verlag Stuttgart.
