    • There were, however, around 2% each of C6H5CH 2C(CH3)=CH2, C6H5CH= C(CH3)2, HOC6H4CH 2C(CH3)=CH2, and HOC6H 4CH=C-(CH3)2. Independent experiments show that Sc(OTf)3 (1.25 × 10-3 M) catalyzes the dehydration of MPPOH (1.25 × 10-2 M) in CH2Cl 2/CH3CO2H (5:2, v/v) to give 3% of C 6H5CH2C(CH3)=CH2 and 4% of C6H5CH=C(CH3)2 after 40 min at 23 °C. The presence of HOC6H4CH2C(CH 3)=CH2 and HOC6H4CH=C(CH 3)2 in the cyclohexane oxidation by MPPH probably comes from the oxidation of C6H5CH2
    • 2, respectively. Independent experiments also show that this catalytic system attacks aromatic rings faster than aliphatic C-H bonds.
