Abstract

Official abstract text for this publication.

Bisphosphites having at least one unsymmetric outer biphenol unit are useful for the hydroformylation of an olefin.

First claim

Opening claim text (preview).

The invention claimed is: 1. A compound represented by structure I: 2. A complex, comprising: a compound according to claim 1 ; and a metal atom selected from the group consisting of: Rh, Ru, Co, and Ir. 3. A catalyst for catalyzing a hydroformylation reaction, comprising the compound according to claim 1 . 4. A process for hydroformylation of an olefin, comprising: a) initially charging an olefin into a reactor; b) a complex according to claim 2 to the reactor; c) feeding into said reactor H 2 and CO, to obtain a reaction mixture; and d) heating the reaction mixture, to obtain conversion of the olefin to an aldehyde. 5. A process for hydroformylation of an olefin, comprising: a) initially charging an olefin into a reactor; b)adding a compound according to claim 1 and a substance having a metal atom selected from the group consistining of: Rh, Ru, Co, and Ir to the reactor; c) feeding into said reactor H 2 and CO, to obtain a reaction mixture; and d) heating the reaction mixture, to obtain conversion of the olefin to an aldehyde.
