In this report, we demonstrate that a ball-milling technique facilitates fast and efficient silver-catalyzed ring-opening fluorination of cyclobutanols. This is the first report of a catalytic C–Cbond-cleavage/functionalization reaction under solid-state mechanochemical conditions. The developed protocol affords a high yield of γ-fluorinated ketones within much shorter reaction times, and requires less
A visible light-driven, copper-catalyzed aerobic oxidativecleavage of cycloalkanones has been presented. A variety of cycloalkanones with varying ring sizes and various α-substituents reacted well to give the distal keto acids or dicarboxylic acids with moderate to good yields.
