Electron Microscopy (FESEM) and Transmission Electron Microscopy (TEM) analysis, respectively. The catalytic potential of the nanocomposite was scrutinized in the synthesis of monosubstituted ketones via a hydrogen autotransfer strategy and synthesis of azines via dehydrogenative pathway. The products of both reactions were isolated in excellent yields and characterized by nuclear magnetic resonance (NMR)
Aerobic Oxidative Coupling between Carbon Nucleophiles and Allylic Alcohols: A Strategy to Construct β-(Hetero)Aryl Ketones and Aldehydes through Hydrogen Migration
reaction: A highly efficient PdII‐catalyzed intermolecular oxidative‐coupling reaction is reported, inspired by the fundamental Heck and Wacker processes. The (hetero)aryl‐PdX species, originating from CHactivation step or desulfonyl hydrazides, coupled with allylic alcohols by using oxygen as the sole oxidant (see scheme).
