Herein, unprecedented manganese-catalyzed direct α-alkenylation of amides using alcohols is reported. Aryl are reacted with diverse primary alcohols, which provided the α,β-unsaturated in moderate to good yields excellent selectivity. Mechanistic studies indicate that Mn(I) catalyst oxidizes their corresponding aldehydes and also plays an important role efficient C═C bond formation through aldol condensation. This selective olefination facilitated by metal–ligand cooperation aromatization–dearomatization process operating catalytic system. Biorenewable used as alkenylation reagents for challenging highly abundant base metal manganese a catalyst, results water dihydrogen only byproduct, making this transformation attractive, sustainable, environmentally benign.

An efficient cobalt-catalyzed migrational isomerization of styrenes was developed using the thiazoline iminopyridine (TIP) ligand. This reaction is operationally simple and atom-economical readily available starting materials to access trisubstituted alkenes. Even when a 0.1 mol % catalyst loading, could be conducted in neat completed 1 h with excellent conversion high E stereoselectivity.

Herein, an efficient and selective nickel-catalyzed dehydrogenation of five- six-membered N-heterocycles is presented. The transformation occurs in the presence alkyl, alkoxy, chloro, free hydroxyl primary amine, internal terminal olefin, trifluoromethyl, ester functional groups. Synthesis important ligand antimalarial drug quinine demonstrated. Mechanistic studies revealed that cyclic imine serves as key intermediate for this stepwise transformation.
