Small Molecule Activation Using Transfer Hydrogenation Catalysts
Though 1 is not Lewis acidic and does not readily react with H2, the addition of a catalytic amount of acid was found to promote the hydrogenation of 1 to 1H(H). The rate of hydrogenation of 1 was found to be dependent on the identity of the acid. It was found that acids with a pKa three orders of magnitude more acidic than [Cp*Ir(H2)(TsDPEN)] + (pKa = 13.88 in MeCN) resulted in the fastest hydrogenation rate. Using 1 and a catalytic amount of acid, water was produced from an atmosphere containing H2 and O 2.
