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.

The invention relates to the synthesis of tetraphenol-substituted structures, in particular meta-substituted xylenes. Said tetraphenol-type structures are reacted to obtain organic phosphorus compounds, in particular organophosphites. The invention further relates to the production of catalytically active compositions which contain transition metals in addition to the aforementioned organic phosphorus compounds. According to another subject matter of the invention, said catalytically active compositions are used in chemical reactions with small molecules, e.g. HCN, CO, hydrogen, and amines.
