We developed a chromium-catalyzed, photochemical, and linear-selective alkylation of aldehydes with alkylzirconium species generated in situ from a wide range of alkenes and Schwartz’s reagent. Photochemical homolysis of the C–Zr bond afforded alkyl radicals, which were then trapped by a chromium complex catalyst to generate the alkylchromium(III) species for polar addition to aldehydes. The reaction
我们开发了铬催化,光化学和线性选择的醛醛烷基化反应,以及从各种烯烃和Schwartz试剂中就地生成的烷基锆物种。C-Zr键的光化学均质化提供了烷基,然后被铬络合物催化剂捕获,从而生成了烷基铬(III)物种,用于极性加成到醛中。反应在可见光照射下于环境温度下以高官能团耐受性进行。
