a Reactions of 1aa or 1ab with 2a were performed under standard reaction conditions. b Reaction of 1ac with 2a was performed under standard reaction conditions. Reaction of 35 with 2a was performed without the addition of [Cp*RhCl2]2. c in situ IR experiments of 1c and 2a. Me: methyl; Cp*: 1,2,3,4,5-pentamethylcyclopentadiene; 1-MeCHA: 1-methylcyclohexane-1-carboxylic acid; OTf: trifluoromethanesulfonate; DCE: 1,2-dichloroethane.
