Abstract

The deuterioformylation of (Z)‐ or (E)‐2‐butene catalyzed by [DIOP]Pt(SnCl~3~)‐ClDIOP=2,3‐O‐isopropylidene‐2,3‐dihydroxy‐1,4‐bis(diphenylphosphino)butane.

gives predominantly erythro‐ or threo‐1,3‐[^2^H]~2~‐2‐methylbutanal respectively. Hence, hydroformylation by this catalytic system must take place with cis‐stereochemistry.

## Abstract The asymmetric hydroformylation of the straight chain butenes with the [(−)‐DIOP]PtCl~2~‐SnCl~2~ catalytic system shows that asymmetric induction, contrary to the rhodium‐(−)‐DIOP catalytic system, takes place after the intermediate metal‐alkyl‐complex formation.

The homogeneously catalyzed hydroformylation of linear olefins was investigated at pressures ranging from 7 to 550 MPa. A change in the selectivity was observed, which was reflected by a change of the product distribution. At high-pressures, increased yields of aldehydes were also obtained from the
