A method is proposed to prepare 4-aryltetrahydropyridines by a Pd-catalyzed cross-coupling reaction by using tosylhydrazone as the nucleophilic coupling agent without stoichiometric organometallic reagent. Palladium-catalyzed couplings can be used for the formation of C-C linkages. It was observed during study that tosylhydrazone can be generated by employing 4-piperidones directly in the cross-coupling reaction with tetrahydropyridines in very high yields. It was also found during study that the ketones and aldehydes can be employed as nucleophilic coupling partners in a reaction without using stoichiometric organometallic reagent. The study concluded that the method can be used to prepare different types of di- and trisubstituted olefins at large scale.
