Ligands for use with catalyst compositions used in hydroformylation reactions are described herein. The ligands are used with various octofluorotoluene or hydrocarbon solvents and achieve an increase in isoselectivity with an increase in temperature, an increase in TON with an increase in temperature, and/or will show isoselectivity that is surprisingly high in comparison to the hydroformylation reactions using common solvents.

Processes for preparing aldehydes from olefins under hydroformy!ation temperature and pressure conditions are disclosed. The processes include a step of contacting at least one olefin with hydrogen and carbon monoxide in the presence of at least one solvent and a transition metal-based catalyst composition comprising a bisphosphine ligand.
