    Abstract: An improved process for the synthesis of zerovalent nickel catalyst useful for the hydrocyanation of olefins, wherein catalyst formation is improved by applying sonication during formation of catalyst. The sonication may be applied to the catalyst reactant mixture containing elemental nickel and a ligand; or alternatively, the sonication may be applied to the elemental nickel prior to the addition of ligand to the reaction mixture.

    Abstract translation: 用于合成可用于烯烃氢化氰化的零价镍催化剂的改进方法,其中通过在催化剂形成期间应用超声处理来改善催化剂形成。 超声处理可以应用于含有元素镍和配体的催化剂反应物混合物; 或者,在将配体加入到反应混合物之前,可以将超声处理施加到元素镍上。
