Supramolecular hydroformylation catalyst

PCT/EP2024/057727 & WO2024200242The invention refers to a hydroformylation catalyst of formula (I), which comprises a rhodium complex. It also refers to a process for preparing the catalyst, and to the use of the catalyst in hydroformylation reactions which show higher regioselectivity in favor or linear aldehydes, as well as higher conversion yields. It also refers to a ligand and a process for preparing the ligand. It refers also to a process for preparing aldehydes by a hydroformylation reaction.
