In this work, we disclosed that diphenyl oxalate serves as a CO surrogate to enable a Ni-catalyzed carbonylation of alkyl bromides/tosylates to afford dialkylketones. The reaction shows broad substrate scope and good functional group tolerance.
在这项工作中,我们公开了草酸二苯酯作为 CO 替代物,使 Ni 催化的烷基溴化物/甲苯磺酸盐羰基化得到二烷基酮。该反应显示出广泛的底物范围和良好的官能团耐受性。
The present invention is directed to tricyclic indole derivatives, pharmaceutical compositions containing them and their use in the treatment of disorders and conditions modulated by endothelial lipase, for example, cardiovascular disorders.
reactivity and selectivity control of unactivatedalkyl halides. Here we report a general strategy for electrochemical cross-electrophile coupling of unactivatedalkyl halides under nickel catalysis. The highly selective electrochemical cross-electrophile coupling process was carried out in an operationally simple manner with high selectivity, setting the stage for the challenging C(sp3)–C(sp3) bonds
