Process for the direct conversion of alkenes to carboxylic acids.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the direct conversion of alkene to the corresponding carboxylic acid comprising: a) adding an alkene, forming a reaction mixture; b) adding a complex, comprising a compound according to structure ( 1 ) and also Pd, or a compound according to structure ( 1 ) and a substance comprising Pd c) feeding in CO; d) heating the reaction mixture such that the alkene and CO are directly to the corresponding carboxylic acid. 2. The process according to claim 1 , wherein the substance in process step b) is PdCl 2 , PdBr 2 , Pd(acac) 2 , Pd(dba) 2 (dba=dibenzylideneacetone) or PdCl 2 (CH 3 CN) 2 . 3. The process according to claim 1 , wherein the process comprises the additional process step e): e) addition of acetic acid. 4. The process according to claim 1 , wherein the process comprises additional process step f): f) addition of water. 5. The process according to claim 1 , wherein the process comprises the additional process step g): g) addition of p-toluenesulfonic acid. 6. The process according to claim 1 , wherein the reaction mixture is heated to a temperature in the range from 80° C. to 160° C. in process step d). 7. The process according to claim 1 , wherein the CO is fed in in process step c) such that the reaction proceeds under a CO pressure in the range from 20 bar to 60 bar. 8. The process of claim 1 wherein the corresponding carboxylic acid is an iso or n/iso mixture. 9. The process of claim 1 wherein the alkene is cyclic or acyclic compound and the acyclic carbon-carbon double bond is characterized as primary and the corresponding carboxylic acid is a mixture.
