A new functional‐group tolerant, rhodium‐catalyzed, sulfide‐reduction process is combined with rhodium‐catalyzed chelation‐controlled hydroacylation reactions to give a traceless hydroacylation protocol. Aryl‐ and alkenyl aldehydes can be combined with both alkenes, alkynes and allenes to give traceless products in high yields. A preliminary mechanistic proposal is also presented.
一种新的能够耐受铑的催化,硫化物还原的功能基团,与铑催化的螯合控制的加氢酰化反应相结合,形成了无痕的加氢酰化方案。芳基和烯基醛可与烯烃,炔烃和丙二烯结合使用,以高收率得到无痕产物。还提出了初步的机械建议。
