The high-yield synthesis of functionalized dodecaborates has become of recent interest due to their application in fields such as pollution remediation, cancer therapies, and clean energy production. To that end, we investigated the palladium-catalyzed carbonylation of the iodododecaborate B12H11I2- under microwave conditions. The addition of CO to B12H11I2- to produce B12H11CO- was achieved in high yield using a variety of commercially-available palladium catalysts, with best results achieved by using Mo(CO)6 as a CO source. Reactions utilizing amines as in situ trapping agents provided B12H11CO(NR2)-. Products were characterized by 11B, 1H and 13C NMR, ESI-MS, and x-ray crystallography.
