WebAbstract. Electron-deficient olefin (EDO) ligands are known to promote a variety of nickel-catalyzed cross-coupling reactions, presumably by accelerating the reductive elimination step and preventing undesired β-hydride elimination. While there is a growing body of experimental and computational evidence elucidating the beneficial effects of ...

WebAug 20, 1999 · In the presence of catalytic amounts of cesium hydroxide (CsOH·H 2 O), alcohols, substituted anilines and heterocyclic amines undergo an addition in NMP to phenylacetylene leading to functionalized enol ethers and enamines. Anilines add to styrene (90–120°C, 12–14 h) leading to N-substituted anilines in satisfactory yields. WebThieme E-Books & E-Journals. Abstract. A catalytic system consisting of Ni(acac) 2 (5 mol%) and 4-fluorostyrene (20 mol%) allows a convenient cross-coupling of functionalized organomanganese reagents with a variety of aryl and heteroaryl halides leading to polyfunctionalized diaryl- and arylheteroarylmethane derivatives.
