Radical Phosphination of Organic Halides and Alkyl Imidazole-1-carbothioates
摘要:
Taking advantage of a radical-based methodology, mild and chemoselective phosphination reactions of organic halide and alkyl imidazole-1-carbothioates have been developed. The mild reaction conditions allow labile functional groups to survive during the reaction.

Various triarylphosphines have been prepared by coupling diphenylphosphine with aryl iodides with catalytic amounts of CuI in the presence of either K2CO3 or Cs2CO3, in good yields. This method can tolerate a variety of functional groups and does not require the use of expensive additives, or harsh reaction conditions, and is palladium free.

mechanism of sodium phosphide R2PNa and other alkali metal phosphides R2PM (M = Li and K) have been studied. R2PNa could be prepared, accurately and selectively, via the reactions of SD (sodium finely dispersed in mineral oil) with phosphinites R2POR′ and chlorophosphines R2PCl. R2PNa could also be prepared from triarylphosphines and diarylphosphines via the selective cleavage of C–P bonds. Na was superior
