Application
With rhodium forms a highly active catalyst for the hydroformylation of α-olefins.

The hydroformylation of functionalized α-olefins is highly regioselective. The sterically demanding ligand increases n/iso ratio by reducing rhodium interaction with heteroatom functionality.

Ligand used in tandem reaction sequences where high n/iso ratio is desired in the hydroformylation step.
