The scope and limitations of the Nickel(0)-catalyzed cross coupling of vinyl triflates with alkyl Grignard reagents have been studied. The effect of triflate substitution, solvent, and especially ligands have been examined. Ligands which are successful for sp2 and sp Grignard reagents fail for sp3 Grignard reagents.
研究了镍三氟甲磺酸与烷基格氏试剂的镍(0)催化交叉偶联的范围和局限性。已经研究了三氟甲磺酸酯取代,溶剂,尤其是配体的作用。成功用于sp 2和sp Grignard试剂的配体不能用于sp 3 Grignard试剂。
