Catalytic hydroxylation of [Closo-B_12H_12]~2-: adaptation of the Periana reaction to a polyhedral borane

摘要

Per-B-hydroxylation of a polyhedral borane anion has been demonstrated by the catalytic hydroxylation of icosahedral [closo-B_12H_12]~2- using soft electrophiles such as platinum group metal catalysts or iodine cation. A new route to [closo-B_12(OH)_12]~~2-from [closo-B_12H_12]~2 without the use of H_2O_2 oxidant provides an alternative hydroxylation process.
