Palladium-catalyzed transformation of cyclobutanone O-benzoyloximes to a variety of nitriles is described. The reaction may proceed via two important steps, that is,(i) oxidative addition of the NO bond of oximes to Pd (0) to give a cyclobutylideneaminopalladium (II) species and (ii) β-carbon elimination of this species to afford a reactive alkylpalladium species. The kind of products is very dependent on the nature of substituents on the cyclobutane ring. The ...
