The selective functionalization of o-carboranes is a popular topic in carborane chemistry. o-Carborane has been widely used in aggregation-induced luminescent materials, nonlinear luminescent materials and other function materials due to its special 3D-aromaticity. The π conjugated systems-tethered o-carboranes could further broaden its applications in the field of luminescent materials. Herein, we have developed a palladium-catalyzed Heck-type mono-alkenylation of o-carboranes featuring phosphine oxide as the directing group.
Key words: palladium, Heck reaction, carborane, B—H activation
