A Pd-II-catalyzed ortho-(Csp(2))-H arylation reaction of benzaldehydes using a catalytic amount of 2-(methylsulfinyl)aniline as transient auxiliary was developed. This reaction is compatible with a broad range of benzaldehyde and aryl iodide substrates. Compared with other related reaction systems, an excellent regioselectivity for ortho-C(sp(2))-H bonds over benzylic C(sp(3))-H bonds was obtained for ortho-alkyl-benzaldehyde substrates.
