Abstract

Abstract : A bifunctional O -tethered Ir complex containing a 1, 2-diphenylethylenediamine framework is newly developed. The tether linkage contributes to exceptional durability in the catalytic dehydrogenation from formic acid by hampering deactivation pathways. Abstract : A bifunctional tethered iridium catalyst containing a 1, 2-diphenylethylenediamine framework was synthesised for the first time. The ethereal tether chain was easily constructed via the intramolecular oxydefluorination of a perfluorophenylsulfonyl substituent by using a modified 1, 2, 3, 4, 5-pentamethylcyclopentadienyl ligand with a hydroxyalkyl chain. The conformationally constrained structure could hamper deactivation pathways in the catalytic hydrogen generation from formic acid, leading to advanced durability and complete conversion.
