  organozinc reagents with aryl electrophiles using a cyclohexyl‐YPhos ligand bearing an ortho‐tolyl‐substituent in the backbone. This highly electron‐rich, bulky ligand enables the use of aryl chlorides in room temperature couplings of Reformatsky reagents. The reaction scope covers diversely functionalized arylacetic and arylpropionic acid derivatives. Aryl bromides and chlorides can be converted selectively

  芳基氯化物与Reformatsky试剂的偶联是构建α-芳基酯的理想策略，但由于各种可能的副反应带来许多挑战，到目前为止，在基质范围上已受到很大的限制。现在，通过调整内酯官能化的膦以满足Negishi联轴器的要求，克服了这一局限性。使用在主链上带有邻甲苯基取代基的环己基-YPhos配体，在钯催化的有机锌试剂与芳基亲电试剂的芳基化中达到了创纪录的活性。这种高度电子富集的庞大配体使得可以在Reformatsky试剂的室温偶联中使用芳基氯化物。反应范围包括各种官能化的芳酸和芳基丙酸衍生物。

  nickel-catalyzed, manganese-mediated cross-electrophile coupling between aryl and alkyl bromides. In addition to the traditional reaction parameters, mechanical ones, e.g. the rotational speed of mill, the filling degree of jar and ball size, have been found to affect the catalytic efficiency remarkably, implying the involvement of the regeneration of nickel(0) species in the rate-determining steps. A combined evaluation

  液体辅助研磨已成功应用于消除镍催化、锰介导的芳基和烷基溴之间的交叉亲电偶联中对化学活化剂和无水溶剂的要求。除了传统的反应参数外，机械参数，如磨机的转速、罐子的填充程度和球的大小，已被发现显着影响催化效率，这意味着镍 (0) 物种的再生参与了速率决定步骤。对反应和机械参数的综合评估导致了最佳条件，在该条件下，各种n具有各种官能团的烷基芳烃可以在 1 mol% 的催化剂负载下以良好的收率轻松获得。液体辅助研磨使芳基/烷基交叉亲电偶联的实际应用已在 6-甲氧基四氢萘酮的克级合成中得到证明。

  Reductive cross-coupling allows the direct C–C bond formation between two organic halides without the need for preformation of an organometallic reagent. A method has been developed for the reductive cross-coupling of nonaromatic, heterocyclic bromides with aryl or heteroaryl bromides. The developed conditions use an air-stable Ni(II) source in the presence of a diamine ligand and a metal reductant

  还原性交叉偶联可在两种有机卤化物之间直接形成C-C键，而无需预先形成有机金属试剂。已经开发出一种用于将非芳香族杂环溴化物与芳基或杂芳基溴化物进行还原性交叉偶联的方法。所开发的条件在二胺配体和金属还原剂的存在下使用空气稳定的Ni（II）源，以使饱和杂环能够以耐官能团的方式后期结合到芳基卤化物上。
