Abstract:
1. A process for producing a cyano ring-substituted arene borane wherein the arene is selected from the group consisting of pyridine, pyrrole, furan, thiophene and benzene, the process comprising: reacting a ring-substituted cyano arene with an HB or a B—B organic compound, in the presence of a catalytically effective amount of a catalytic composition comprising an iridium complex and an organic ligand at least in part bonded to the iridium complex, the organic ligand being selected from the group consisting of a phosphorus organic ligand, an organic amine, an imine, and a nitrogen-substituent organic ligand comprising at least one 5- or 6-membered nitrogen heterocycle to form the cyano ring-substituted arene borane; wherein: (i) the iridium complex is selected from the group consisting of (Cp*)Ir(H) (ii) in the iridium complex, CP* is 1,2,3,4,5-methylcyclopentadienyl, BPin is pinacolborane, Me is methyl, H is hydrogen, P is phosphorus, Ind is indenyl, COD is 1,5-cyclooctadiene, MesH is mesitylene, and R, R
