    日期:2021.8.16
    Herein, the photocatalytic hydrosilylation of alkynes and alkenes under continuous flow conditions is described. By using 0.2 mol % of the developed [Cu(dmp)(XantphosTEPD)]PF6 under blue LEDs irradiation, a large panel of alkenes and alkynes was hydrosilylated in good to excellent yields with a large functional group tolerance. The mechanism of the reaction was studied, and a plausible scenario was
    在此,描述了在连续流动条件下炔烃和烯烃的光催化氢化硅烷化。通过在蓝光 LED 照射下使用 0.2 mol% 开发的 [Cu(dmp)(XantphosTEPD)]PF 6,大量烯烃和炔烃被氢化硅烷化,产率良好至极好,具有较大的官能团耐受性。研究了反应的机理,并提出了一个可能的假设。

    作者:Li-Jie Cheng、Neal P. Mankad
    DOI:10.1021/jacs.9b12043
    日期:2020.1.8
    A Cu-catalyzed carbonylative silylation of unactivated alkyl halides has been developed, enabling efficient synthesis of alkyl-substituted acylsilanes in high yield. A variety of functional groups are tolerated under the mild reaction conditions, and primary, secondary and tertiary alkyl halides are all applicable. The practical utility of this method has been demonstrated in the synthesis of acylsilanes

    DOI:10.1002/anie.201906825
    日期:2019.9.2
    A number of new magnesium and lithium silyl reagents were prepared and shown to be outstanding nucleophiles in reactions with industrially relevant fluoroolefins. These reactions result in a net transformation of either sp2 or sp3 C-F bonds into C-Si bonds by two modes of nucleophilic attack (SN V or SN 2'). The methods are mild, proceeding with high chemo- and regioselectivity. Mechanistic pathways
