Abstract
Ligands for use with catalyst compositions used in hydroformylation reactions are described herein. The ligands are used with various ester 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.
