Tetraphenol-based diphosphite ligands: synthesis, characterization, and application in the rhodium-catalyzed hydroformylation of octenes
摘要:
A new class of diphosphites is described, based on a tetraphenol backbone. Ligands TP1-TP5 were synthesized and fully characterized and their application in the hydroformylation of octenes was investigated. Ligand TP3, bearing a 1-naphthoxy substituent on the phosphorus, shows the highest regioselectivity toward the linear aldehyde. (C) 2010 Elsevier Ltd. All rights reserved.
