Light-enabled alkenylation of iodocarboranes with unactivated alkenes

A synthetic method to alkenylated-o-carboranes via photoalkenylation of iodocarboranes with unactivated alkenes has been achieved. This strategy features a transition-metal-free protocol, light-promoted reaction with mild reaction condition, broad substrate scope and good functional group tolerance. Control experiments suggest that the reaction may involve the cage C-centered radical species.
