Hydrocarboxylation of alkynes: The first example of nickel‐catalyzed hydrozincation of alkynes that form stereodefined hydrocarboxylation products is presented (see scheme; cod=cycloocta‐1,5‐diene). This catalytic system is efficient for the activation of CO2 and the three‐component reaction produces products that could be converted into important oxindole or γ‐butyrolactam derivatives.
炔烃的加氢羧化:提出了镍催化炔烃形成立体定义的加氢羧化产物的第一个例子(见方案; cod = cycloocta-1,5-diene)。该催化体系对CO 2的活化非常有效,三组分反应产生的产物可以转化为重要的羟吲哚或γ-丁内酰胺衍生物。
