2,2'-Carbonylbibenzimidazole Ligand-Based Hyper-Cross-Linked Polymer-Supported Iridium Complex: A Recyclable Metal-Polymer Ligand Bifunctional Catalyst for Upgrading Ethanol to n-Butanol.

Key Points

• This research aims to develop a recyclable catalyst to efficiently upgrade ethanol to n-butanol.
• Mechanistic investigations were conducted using density functional theory calculations.
• The catalyst was tested for its activity over six consecutive runs.
• The catalyst achieved up to 37% yield of n-butanol.
• It maintained significant activity after six reuse cycles.
