Abstract:
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.

Claim (Index 41):
A transition metal-based catalyst composition comprising a phospholane phosphite ligand represented by the following general formula: wherein:\n R1 and R2 are independently selected from substituted and unsubstituted, aryl, alkyl, aryloxy or cycloalkyl groups containing from 1 to 40 carbon atoms; \n R3 and R4 are independently selected from substituted and unsubstituted, aryl, alkyl, alkoxy, trialkylsilyl, triarylsilyl, aryldialkylsilyl diarylalkylsilyl and cycloalkyl groups containing from 1 to 20 carbon atoms, wherein the silicon atom of the alkylsilyl is in the alpha position of the substituent; and \n R5 is independently selected from H, or alkyl group.
