摘要：

(Chemical Equation Presented) A tailored hybrid mesostructured material containing regularly distributed imidazolium units, and subsequent transformation of these imidazolium moieties into Ir-NHC (NHC = N-heterocyclic carbene) complexes via the formation of Ag-NHC species in situ and further transmetalation with [{IrCp*Cl2}2], gives a well-defined, active,and reusable Ir-NHC heterogeneous catalyst for H/D exchange reactions (see picture). © 2008 Wiley-VCH Verlag GmbH & Co.
