The development of efficient methods for the direct introduction a methyl group into molecules is becoming increasingly important. Herein, β-methylation primary alcohols with methanol has been accomplished under environmentally benign conditions using [Cp*Ir(2,2′-bpyO)(H2O)] as catalyst. It was found that functional groups in ligand are crucially important activity iridium complex. Furthermore, mechanistic research and application potential our catalytic system also presented.

A water-soluble iridium complex [Cp*Ir(6,6′-(OH)2-2,2′-bpy)(H2O)][OTf]2 was found to be an efficient autotandem catalyst for the synthesis of secondary alcohols via redox isomerization/atmospheric hydrogenation in water. The OH groups bpy ligand are a key factor activity catalyst. Then, mechanistic experiments and practical utilization catalytic system were presented.
