Abstract

Official abstract text for this publication.

A catalytic method for hydroformylating cyclooctadiene substrate involving forming a reaction mixture that includes the cyclooctadiene and a precursor of or a transitional metal ligand complex where the ligand has structure (1): (1) H 2 and CO are fed into the reaction mixture and the mixture is heated to convert the cyclooctadiene into an aldehyde. A preferred ligand is 4-([1,1′:3′,1″-terphenyl]-2′-yloxy)-S-dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for hydroformylating cyclooctadiene, comprising the method steps of: a) initially charging cyclooctadiene; b) adding a complex comprising: a metal atom selected from: Rh, Ru, Co, Ir, and a ligand having the structure (1): or adding a precursor complex comprising a metal atom selected from: Rh, Ru, Co, lr, and a compound having the structure (1): c) feeding in H 2 and CO, d) heating the reaction mixture, wherein the cyclooctadiene is converted to an aldehyde. 2. The method according to claim 1 , wherein the metal atom is Rh. 3. The method according to claim 1 , wherein the precursor complex comprises cyclooctadiene. 4. The method according to claim 1 , wherein the precursor complex is [(acac)Rh(COD)]. 5. The method according to claim 1 , wherein the reaction mixture is heated to a temperature in the range of 50° C. to 70° C. in method step d).
