On the basis of deuterium labeling experiments and an equal 1,2-/1,4-product distribution, the reductive elimination of the product has been established to be the enantioselective step in the nickel-catalyzed hydrocyanation of 1,3-cyclohexadiene. This could be achieved by successfully exploiting the rather unique features of this reaction: identical product formation for 1,2- and 1,4-addition, cis
基于氘标记实验和相等的 1,2-/1,4-产物分布,产物的还原消除已被确定为镍催化 1,3-环己二烯氢氰化反应中的对映选择性步骤。这可以通过成功利用该反应的相当独特的特征来实现:1,2-和1,4-加成形成相同的产物,二烯上的顺式加成以及高对映体过量。
