The combination of a bidentate-sulfoxide-ligated palladium complex combined and Ag2CO3 catalyzes an allylic C-H acyloxylation of terminal alkenes with 4-nitrobenzoic acid in the presence of 1,4-benzoquinone under mild reaction conditions. Ag2CO3 as an additive and 4-nitrobenzoic acid as a carboxylate source were essential to exhibiting high catalytic activity and regioselectivity.
