Nickel-Catalyzed Cross-Coupling Reactions of Alkyl Aryl Sulfides and Alkenyl Alkyl Sulfides with Alkyl Grignard Reagents Using (<i>Z</i>)-3,3-Dimethyl-1,2-bis(diphenylphosphino)but-1-ene as Ligand
A combination of nickel(II) acetylacetonate and (Z)-3,3-dimethyl-1,2-bis(diphenylphosphino)but-1-ene catalyzes cross-couplingreactions of alkyl aryl sulfides and alkenyl alkyl sulfides with alkyl Grignardreagents. Not only primary but also secondary alkyl Grignardreagents can be employed.

A nickel-catalyzed thiolation of aryl nitriles has been developed to access functionalized aryl thioethers. The ligand dcype (1,2-bis(dicyclohexylphosphino)ethane) as well as the base KOtBu (potassium tert-butoxide) are essential to achieve this transformation. This scalable and practical process involves both a C−C bond activation and a C−S bond formation. Furthermore, this reaction shows a high functional-group
已开发出镍催化的芳基腈硫醇化反应以获得官能化芳基硫醚。配体 dcype(1,2-双(二环己基膦基)乙烷)以及碱基 KO t Bu(叔丁醇钾)对于实现这种转变至关重要。这种可扩展且实用的过程涉及 C−C 键激活和 C−S 键形成。此外,该反应表现出高官能团耐受性,并能够实现重要分子的后期官能化。
