A highly efficient semireduction of alkynes has been developed. Using 0.5–2 mol % of a copper catalyst, semireduction can be accomplished with a wide range of substrates, including both internal and terminal alkynes without over-reduction. The new method has excellent chemoselectivity, and the semireduction can be accomplished even in the presence of nitro and aryl iodo groups. Finally, commercial
已经开发了高效的炔烃半还原。使用0.5–2 mol%的铜催化剂,可以用多种底物完成半还原反应,包括内部炔烃和末端炔烃,而不会过度还原。该新方法具有优异的化学选择性,并且即使在硝基和芳基碘基的存在下也可以完成半还原。最后,催化剂前体的商业可获得性增加了新催化系统的吸引力。
