Palladium-catalyzed cross-coupling reaction of 1,1-diboryl-1-alkenes with aryl and alkenyl iodides proceeded stereoselectively to the corresponding mono-coupled product as a single diastereomer. A subsequent coupling with another aryl iodide afforded various triarylalkenes in their stereochemically pure form.
