Origins of regioselectivity and alkene-directing effects in nickel-catalyzed reductive coupling reactions were investigated by density functional calculations. Regioselectivity of simple alkynes is controlled by steric effects, while conjugated enynes and diynes are predicted to have increased reactivity and very high regioselectivities, placing alkenyl or alkynyl groups distal to the forming C–C bond. The reactions of enynes and diynes involve 1,4-attack on the conjugated enyne of the Ni-carbonyl complex on the conjugated enyne or diyne.
