Palladium-catalyzed cross-coupling reactions of arylboronic acids and 2-I-p-carborane

p-Carborane has been arylated on the 2-B-atom in high yields, using the Suzuki–Miyaura reaction. Thus the reaction between 2-I-p-carborane and various arylboronic acids [1-naphthyl-, phenyl-, 4-MeOC6H4, 3-CH3CONHC6H4, 4-NCC6H4, 3-NO2C6H4], gave the corresponding 2-aryl-p-carboranes in DME solution when reacted in the presence of cesium fluoride and the catalytic Pd2(dba)3–dppb system.
