Synthesis of novel rhodium phosphite catalysts for efficient and selective isomerization–hydroformylation reactions

New modular H8-BINOL-based phosphite ligands have been synthesized. High activity and regioselectivity has been achieved in the rhodium-catalyzed isomerization–hydroformylation of internal olefins. The active catalysts have been characterized by insitu NMR studies.

Graphical abstractNew modular bisphosphite ligands have been conveniently synthesized. The corresponding rhodium complexes are highly active catalysts for isomerization–hydroformylation reactions of internal olefins.
