Provided is a method of synthesizing a C(sp3)-C(sp2) cross-coupled compound comprising reacting a C(sp3) coupling partner with a C(sp2) coupling partner, a catalyst, and a solvent; wherein the C(sp3) coupling partner comprises an organic zinc reagent; and wherein the C(sp2) coupling partner comprises a heterocyclic halide or a heterocyclic pseudo halide. The method further comprises synthesis of the organic zinc reagent, wherein the synthesis comprises reacting a zinc powder with an acid, filtering, washing, and drying to obtain an activated zinc powder; and reacting the activated zinc powder with a metal iodide catalyst and a second solvent and heating for a predetermined time to obtain the organic zinc reagent.
提供了一种合成C(sp3)-C(sp2)交叉偶联化合物的方法,包括将一个C(sp3)偶联配体与一个C(sp2)偶联配体、催化剂和溶剂反应;其中C(sp3)偶联配体包括有机锌试剂;而C(sp2)偶联配体包括杂环卤化物或杂环假卤化物。该方法进一步包括合成有机锌试剂,其中合成包括将锌粉与酸反应,过滤,洗涤和干燥以获得活化锌粉;并将活化锌粉与金属碘催化剂和第二溶剂反应并加热一定时间以获得有机锌试剂。
