17 For an example of Pd-catalyzed aerobic allylic oxygenation of
terminal alkenes DMA showed to be the most effective solvent in
promoting the reoxidation of the Pd0 species by O2 and
simultaneously suppressing competing Pd0 aggregation, see: T.
Mitsudome, T. Umetani, N. Nosaka, K. Mori, T. Mizugaki, K.
Ebitani and K. Kaneda, Angew. Chem. Int. Ed., 2006, 45, 481.
18 The precise reason that fluorine atoms shut down reactivity is unclear
in the present stage and remains to be elucidated.
19 When anhydrous DMSO was used as the solvent, the reaction mainly
led to (E)-butyl cinnamyl ether 5aa and its derivatives. For details,
see the Supporting Information Table 4.
20 The detection of a small amount of 3aa can be explained that only a
little water which generated from the first-step oxygenation process,
underwent the second-step oxygenation.
