A highly regio- and stereoselective hydrocyanation of 1,3-enynes was implemented by nickel/diphosphine catalysts. A wide range of highly regio- and stereoselective alkenyl nitriles were efficiently prepared. In this transformation, both the tethered alkene and the ligand play key roles in the reactivity and selectivity. The origin of regioselectivity was understood preliminarily by DFT studies.
镍/二膦催化剂实现了1,3-烯的高度区域和立体选择性氢氰化。有效地制备了多种高度区域选择性和立体选择性的烯基腈。在该转化中,束缚的链烯和配体均在反应性和选择性中起关键作用。DFT研究初步了解了区域选择性的起源。
