A complete
switch in the Cp*Ir(III)-catalyzed paths between C–H
olefination and hydroarylation was found to be crucially dependent
on the type of directing groups. This dichotomy in product distribution
was correlated to the efficiency in attaining syn-coplanarity of olefin-inserted 7-membered iridacycles. Theoretical
studies support our hypothesis that the degree of flexibility of this
key intermediate modulates the β-H elimination, which ultimately
affords the observed chemoselectivity.
