Iridium-Catalyzed Ring Cleavage Reaction of Cyclobutanone <i>O</i>-Benzoyloximes Providing Nitriles

Abstract

[reaction: see text] Iridium-catalyzed ring cleavage reaction of cyclobutanone O-benzoyloximes in the presence of 9,10-dihydroanthracene and potassium carbonate proceeds to give saturated nitriles via C-C bond fission at the sterically more hindered site.
