Reaction inhibition of phenol formation with the addition of 25 equiv of poly(4-vinylpyridine) at t = 0 ( ) and 2 h ( ) using the following starting substrate: (A) cyclohexanone and (B) cyclohexenone. Lack of PVPy (■) addition data is included. Dashed lines indicate cyclohexenone and solid lines indicate phenol formation. Additional time course data is in Figure S8. Reaction conditions: [substrate] = 1 M (0.5 mmol), [Pd(TFA)₂] = 0.05 M (0.025 mmol), [2-Me₂Npy] = 0.1 M (0.05 mmol), [TsOH] = 0.2 M (0.1 mmol), PVPy = 65 mg, DMSO for V_Total of 0.5 mL, 1 atm O₂, 80 °C.
