Coupling reactions nickel iodide

The Ni(ii)/Cr(n)-mediated coupling reaction employs an excess of chromium(ii) chloride and a catalytic amount of nickel(n) chloride (0.1 %). The preferred solvent for this reaction is usually DMF, although THF, DMF/THF, or DMF/Me2S may also be used. The ability to activate the vinyl iodide (or related) substrate at ambient... [Pg.715]

Besides palladium catalysts, nickel was also found to be an effective catalyst for the Sonogashira reaction in aqueous media. Recently, Beletskaya et al. reported a Ni(PPh3)2Cl2/CuI-catalyzed Sonogashira coupling reaction of terminal acetylenes with aryl iodides in aqueous dioxane in high yields (Eq. 4.19).39... [Pg.109]

Unsymmetrical binaphthyls were synthesized by photochemically stimulated reaction of naphthyl iodides with naphthoxide ions in an SrnI reaction. " Methyl chloroacetate coupled with aryl iodides under electrolysis conditions, using a nickel catalyst. " " Unsymmetrical biaryls were prepared from two aryl iodides using a Cul catalyst and microwave irradiation. " ... [Pg.889]
