Enantioselective Intermolecular Heck And Reductive Heck Reactions Of Aryl Triflates, Mesylates, And Tosylates Catalyzed By Nickel

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.
