Herein, a nickel-catalyzed acceptorless dehydrogenative coupling of alcohols with nitriles followed by decyanation of nitriles to access diversely substituted olefins is reported. This unprecedented C=C bond-forming methodology takes place in a tandem manner with the formation of formamide as a sole byproduct. The significant advantages of this strategy are the low-cost nickel catalyst, good functional group compatibility (ether, thioether, halo, cyano, ester, amino, N/O/S heterocycles; 43 examples), synthetic convenience, and high reaction selectivity and efficiency.1 aMidya, Siba, P.1 aSubaramanian, Murugan1 aBabu, Reshma1 aYadav, Vinita1 aBalaraman, Ekambaram  uhttps://library.ncl.res.in/content/tandem-acceptorless-dehydrogenative-coupling-decyanation-under-nickel-catalysis
