Hypervalent iodine compounds usable for arylating reactions

Stuart et al. have designed and synthesized some diaryl-substituted hypervalent iodine compounds having a 1,3,5-trimethoxybenzene (TMB) moiety and an aromatic ring. In these compounds, the TMB moiety acts as a leaving group so that the other aromatic ring can be used for the aryl group introduction. Various functional groups such as cyano, nitro, fluoro, or chloro substituted aromatic TMB hypervalent iodine compounds have been reported so far. It is expected to use these compounds for transition-metal-free arylations.
