Herein, we report a nickel-catalyzed reductive carbonylation reaction of vinyl triflates and alkyl bromides for the preparation of enones. With oxalyl chloride as a safe and readily available carbonyl source, various alkyl alkenyl ketones were prepared in moderate to good yields under relatively mild conditions. Control experiments demonstrated that the combined action of DMF and zinc facilitated the release of CO from oxalyl chloride.

以草酰氯为羰基源的乙烯基三氟乙烯与烷基溴的镍催化还原羰基偶联与烯酮


在此，我们报道了乙烯基三氟磺酸酯和烷基溴的镍催化还原羰基化反应，用于制备烯酮。以草酰氯作为安全且易得的羰基来源，在相对温和的条件下以中等至良好的收率制备了各种烷基烯基酮。对照实验表明，DMF 和锌的联合作用促进了草酰氯中 CO 的释放。
