Abstract

A process for the production of 4-hydroxybutyraldehyde is described. The process comprises reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and a catalyst system comprising a rhodium complex and a trans-1,2-bis(bis(3,5-di-n-alkylphenyl)phosphinomethyl)-cyclobutane. The process gives high yield of 4-hydroxybutyraldehyde compared to 3-hydroxy-2-methylpropionaldehyde.

Claims (4)

1. A catalyst comprising a rhodium complex and a trans-1,2-bis(bis(3,5-di-n-alkylphenyl)phosphinomethyl)cyclobutane.

2. The catalyst of claim 1 wherein the trans-1,2-bis(bis(3,5-di-n-alkylphenyl)phosphinomethyl)cyclobutane is trans-1,2-bis(bis(3,5-di-methylphenyl)phosphinomethyl)cyclobutane.

3. The catalyst of claim 1 wherein the trans-1,2-bis(bis(3,5-di-n-alkylphenyl)phosphinomethyl)cyclobutane is trans-1,2-bis(bis(3,5-di-ethylphenyl)phosphinomethyl)cyclobutane.

4. The catalyst of claim 1 wherein the rhodium complex comprises rhodium and ligands selected from the group consisting of hydride, carbonyl, trialkyl or triaryl phosphines, diphosphines, cyclopentadienyls, 2,4-alkanedionates, and mixtures thereof.
