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.
