In a Cu-catalyzed aerobic oxidative esterification of simple ketones via C-C bond cleavage, various common ketones, even inactive aryl long-chain alkyl ketones, are selectively converted into esters. The reaction tolerates a wide range of alcohols, including primary and secondary alcohols, chiral alcohols with retention of the configuration and electron-deficient phenols.
