Conversion of haloform to carbonate by iridium N-heterocyclic carbene complexes and silver(i) oxide†
Abstract
The reaction between haloform, the complexes [Cp*IrCl2(κC-MeNC3H2NCH2Ar)] (Ar = C6H3F2-2,6, C6H3F-2-Cl-6, C6H3Me2-2,6) and silver(I) oxide proceeded by carbon–halogen bond fission to yield the carbonate complexes [Cp*Ir(κ2O-CO3)(κC-MeNC3H2NCH2Ar)].
