A range of functional aryl and heteroaryl zinc reagents were prepared in THF via directed zincation using the previously reported amide base tmpZnCl·LiCl. These metalation reactions were carried out on 50 mmol scale. Diverse sensitive functional groups such as a nitro group, an aldehyde, an ester, and a nitrile are tolerated. Furthermore, the resulting zinc intermediates show excellent reactivity towards
使用先前报道的酰胺基tmpZnCl·LiCl,通过定向
锌化反应在THF中制备了一系列功能性芳基和杂芳基
锌试剂。这些
金属化反应以50mmol规模进行。容许各种敏感的官能团,例如硝基,醛,酯和腈。此外,所得的
锌中间体显示出对各种类型的亲电试剂的优异反应性,例如Pd催化的交叉偶联反应或Cu催化的酰化和烯丙基化。在所有情况下,均已将
金属化速率与相应的小规模反应(1-2 mmol)进行了比较。此外,已经证明了从
水相中回收有价值的tmp-H。
