On September 22, 2022, Ren, Cheng; Ji, Guanghao; Li, Xiankai; Zhang, Jing published an article.Name: Methyl 2-cyclopentanonecarboxylate The title of the article was Direct Synthesis of Adipic Esters and Adiponitrile via Photoassisted Cobalt-Catalyzed Alkene Hydrodimerization. And the article contained the following:
A cobalt-catalyzed tail-to-tail hydrodimerization of activated alkenes CH2=CHR (R = C(O)2Me, C(O)Ph, C(O)NHPh, etc.) driven by a visible-light photoredox catalysis at ambient temperature, which is applicable to both adipates R(CH2)4R (R = C(O)2Me, C(O)2Ph, C(O)2CH2Ph, etc.) and adiponitrile synthesis from potentially renewable feedstocks has been described. This protocol utilizes half equivalent of hantzsch ester as a recyclable two-electron and two-proton donor with the assistance of catalytic amount of base as a proton shuttle, and has been shown to be highly regioselective and efficient for hydrodimerizing various activated alkenes to 1,4-difunctionalized butane derivatives The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Name: Methyl 2-cyclopentanonecarboxylate
