A palladium-catalyzed, silver-mediated Heck coupling between arylvinyl MIDA boronate esters and aryl iodides is disclosed. The reaction provides an efficient and modular access to a range of 1,1-diaryl alkenyl MIDA boronates that can be easily transformed into triarylethylene compounds through a Suzuki coupling.
