In the presence of PdCl2(MeCN)2, 1,4-benzoquinone, and t-BuOH, aryl-substituted olefins can selectively be oxidized to aldehydes. In this efficient and aldehyde-selective Wacker oxidation, very good yield of aldehyde can be obtained, and up to 99% selectivity can be achieved with styrene-related substrates.
