radicals at the B3, B4, and B9 sites via a visible-light-promoted palladium(0)/palladium(I) pathway using readily available iodo-o-carboranes as the starting materials. The electrophilicities of these hypervalent boron-centered radicals decrease in the following order: B3 > B4 > B9. They are useful intermediates for the preparation of a family of cage B-(hetero)arylated o-carboranes at ambient temperature

This work describes a general method for the synthesis of a series of sulfenylated and selenylated carboranes at room temperature using readily available iodocarboranes as starting materials viaboron-centeredcarboranylradicals. Such hypervalent boron radicals are generated by a visible-light-promoted Pd(0)/Pd(I) pathway. They are useful intermediates and can be trapped by disulfides and phenylselenyl
