A catalytic aromatization of cyclohexene to benzene is described by using [IrH2(Me2CO)2L2]SbF6 (L = PPh3) as catalyst in refluxing 1,2-C2H4Cl2. tert-Butylethylene (tbe) acts as hydrogen acceptor; in the absence of tbe, 2 equiv of cyclohexane are formed per mole of benzene. A mechanism is suggested based on the isolation of the proposed intermediates [Ir(η5-C6H7)HL2]SbF6 and [Ir(η6-C6H6)L2]SbF6. Some reactions of these complexes are discussed.
