Nickel‐catalyzed intermolecular Heck reaction of cycloalkenes proceeds well with aryl triflates, mesylates and tosylates in excellent enantiomeric ratios. The asymmetric reductive Heck reaction also works with a 2‐cyclopentenone ketal, which is equivalent to conjugate arylation of the enone itself.
镍催化的环烯烃的分子间Heck反应与芳基三氟甲磺酸酯,甲磺酸酯和甲苯磺酸酯的对映体比率极好。不对称的还原性Heck反应也适用于2-环戊烯酮缩酮,这相当于烯酮本身的共轭芳基化。
