We describe an unprecedented catalytic dehydrogenation of glucose by homogeneous catalysts. Iridium
(
III
) complexes containing the fragment [Cp*Ir(NHC)]
2+
(NHC = N-heterocyclic carbene ligand) are shown
to be very active and highly selective catalysts for the dehydrogenation of glucose to gluconic acid and
molecular hydrogen. Glucose is converted to gluconic acid at a catalyst loading of 2 mol%, at re
fl
ux in
water, without additives and with a selectivity of over 95%. Experimental evidence obtained by
1
H NMR
spectroscopy and mass spectrometry (ESI/MS) reveals the formation of iridium coordinated to glucose
and gluconic acid species. A plausible mechanism is proposed, based on the experimental evidence and
supported by DFT calculations. [-]
