A Ni/1-bpp catalyst was demonstrated to be effective in the Negishi alkylation with multiple classes of alkylpyridinium salts, including α-primary and α-secondary. These conditions are also effective for benzylic pyridinium salts, demonstrating the successful Negishi alkylation of benzylic pyridinium salts for the first time. Further, 14 derivatives of 1-bpp were prepared with a variety of steric and electronic properties to study how these changes impact the success of the Negishi alkylation.
已证明镍/1-联吡啶催化剂在与多类烷基吡啶盐(包括α-伯烷基和α-仲烷基)的根岸烷基化反应中有效。这些条件对苄基吡啶盐也有效,首次证明了苄基吡啶盐成功进行根岸烷基化反应。此外,制备了具有各种空间和电子性质的14种1-联吡啶衍生物,以研究这些变化如何影响根岸烷基化反应的成功率。
