  A simple protocol of manganese catalyzed selective α-alkenylation of ketones using primary alcohols is reported. The reactions proceeded well with a low loading of catalyst (0.3 mol %). The overall transformation operates through O–H bond activation of primary alcohols via dearomatization–aromatization metal ligand cooperation in the catalyst to provide the corresponding aldehydes, which further undergo
