Palladium-Catalyzed Allylic Amidation with N-Heterocycles via sp3 C-H Oxidation
An atom-economic direct intermolecular allylic amidation of electron-deficient tautomerizable N-heterocycles is reported via allylic C-H activation of terminal olefins with a PdCl2 catalyst. The reaction did not require any activators (base or Lewis acid) or external ligands and proceeded with high chemo- (N vs O), regio- (linear vs branched), and stereoselectivity (E vs Z) for a variety of N-heterocycles and terminal olefins. Mechanistic investigation and stoichiometric studies validate the sulfoxide-ligand-assisted allylic C-H bond cleavage to form a pi-allylpalladium intermediate in the reaction pathway. Excellent selectivity was observed during intermolecular competition demonstrating the differential nucleophilicity of N-heterocycles and differential susceptibility of allyl C-H bond cleavage to form pi-allylpalladium complexes directly from terminal olefins.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 253-52-1
