Abstract

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

Claims (15)

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.
