  Processes for making an organozinc reagents are disclosed comprising reacting (A) organomagnesium or organozinc complexes with (B) at least one coordination compound comprising one or more carboxylate groups and/or alcoholate groups and/or tertiary amine groups, optionally in combination with zinc ions and/or lithium ions and/or halide ions, wherein the halide ions are selected from chloride, bromide and iodide, the organozinc complex comprises an aryl group, a heteroaryl group or a benzyl group when the coordinating compound is a chelating polyamine, and the reaction is conducted in the presence of zinc complexed with at least one coordinating compound when reactant (A) comprises at least one organomagnesium complex. The resulting organozinc reagents may optionally be isolated from solvents to obtain a solid reagent. The reagents may be used for making organic compounds via Negishi cross-coupling reactions or via aldehyde and/or ketone oxidative addition reactions. The organozinc reagents are stable and, due to their high selectivity, permit maintenance of sensitive functional groups such as aldehydes during cross-coupling.

  公开了制备有机锌试剂的方法，包括将（A）有机镁或有机锌配合物与（B）至少一种含有一个或多个羧酸基团和/或醇基团和/或三级胺基团的配位化合物反应，可选地与锌离子和/或锂离子和/或卤离子结合，其中卤离子选自氯离子、溴离子和碘离子，当配位化合物为螯合多胺时，有机锌配合物包括芳基、杂环芳基或苄基，当反应物（A）包含至少一种有机镁配合物时，在存在至少一种配位化合物与锌络合物的情况下进行反应。所得的有机锌试剂可以选择性地从溶剂中分离出来以获得固体试剂。这些试剂可用于通过Negishi交叉偶联反应或通过醛和/或酮氧化加成反应制备有机化合物。有机锌试剂稳定，并且由于其高选择性，允许在交叉偶联过程中保持敏感的官能团，如醛基。

  procedure for the direct preparation of triorganoindium reagents from organic halides by means of magnesium insertion in the presence of InCl3 and LiCl is reported (see scheme). The organoindium reagents are obtained in good yields from functionalized aryl, heteroaryl, and alkyl bromides and benzyl chlorides at 25 °C in THF within 4 h. Moreover, the resulting organoindium reagents could be efficiently

  arylmanganese compounds were prepared using commercial manganese powder in the presence of LiCl and catalytic amounts of both 2.5% InCl3 and 2.5% PbCl2 (THF, 0–50 °C). In addition, benzylic manganese reagents are obtained at 25 °C in ca. 70–80% yield (in the absence of LiCl) using commercial manganese powder and catalytic amounts of 2.5% InCl3 and 2.5% PbCl2. The resulting organomanganese reagents undergo

  Powdered organozinc reagents: Various aryl and heteroaryl bromides as well as benzylic chlorides react with Mg and Zn(OPiv)2⋅2 LiCl (OPiv=pivalate) to provide solid organozinc reagents after solvent evaporation. These powders can be stored at room temperature under argon for months and can be manipulated in air for a short time. They undergo smooth Negishi cross‐coupling and carbonyl addition reactions
