Zhou, Xukai published the artcileOlefination via Cu-Mediated Dehydroacylation of Unstrained Ketones, COA of Formula: C12H20O6, the publication is Journal of the American Chemical Society (2021), 143(48), 20042-20048, database is CAplus and MEDLINE.
The dehydroacylation of ketones to olefins was realized under mild conditions, which exhibited a unique reaction pathway involving aromatization-driven C-C cleavage to remove the acyl moiety, followed by Cu-mediated oxidative elimination to form an alkene between the α and β carbons. The newly adopted N’-methylpicolinohydrazonamide (MPHA) reagent was key to enable efficient cleavage of ketone C-C bonds at room temperature Diverse alkyl- and aryl-substituted olefins, dienes and special alkenes were generated with broad functional group tolerance. Strategic applications of this method were also demonstrated.
