Copper(I) Iodide-Assisted Halogen Exchange at Vinylic Positions. Conversion of Vinyl, Vinylene, and Vinylidene Bromides to the Corresponding Iodo Analogs
Palladium-catalyzed phosphorus–carbon bond formation: cross-coupling reactions of alkyl phosphinates with aryl, heteroaryl, alkenyl, benzylic, and allylic halides and triflates
palladium catalysis. This full paper examines the scope and some mechanistic aspects of this phosphorus–carbon bond forming reaction. The reactions of alkenyl and allylichalides are also described for the first time. This novel cross-coupling provides a convenient access to a variety of substituted H-phosphinates.
Copper(I) Iodide-Assisted Halogen Exchange at Vinylic Positions. Conversion of Vinyl, Vinylene, and Vinylidene Bromides to the Corresponding Iodo Analogs
The title bromo olefins undergo the copper(I) iodide-mediated exchange with iodide ion in hot hexamethylphosphoric triamide to give the corresponding iodo analogs in moderate to good yield.
