Abstract

[Cp*Ir(2,2′-bpyO)(H2O)] is a highly efficient and general catalyst for transfer hydrogenation of carbonyl compounds and chemoselective transfer hydrogenation of unsaturated aldehydes with isopropanol under neutral conditions. The reaction tolerates deducible groups such as nitro, cyano, ester, and halide.
