Phenyliodonium zwitterion as an efficient electrophile in the palladium-catalyzed suzuki-type reaction: a novel method for the synthesis of 3-aryl-4-hydroxycoumarins.
[reaction: see text] A palladium-catalyzed coupling reaction of phenyliodonium zwitterions with aryl boronic acids has been developed. The unique characteristics of the mild reaction conditions and convenient synthetic accessibility of phenyliodonium zwitterions make this method a valuable tool for generating diversified 3-aryl-4-hydroxycoumarins.
