While the carbonyl olefination has been extensively studied and well documented, use
               of α-hydroxy ketones as precursors for the carbonyl olefination is not reported, till
               date. Herein, a transition-metal-free and selective Knoevenagel-type deconstructive
               carbonyl olefination of α-hydroxy ketones using arylacetonitriles under mild reaction
               conditions is presented. The reaction affords valuable scaffolds of acrylonitriles
               with the use of α-hydroxy ketones as precursors for carbonyl olefination.
