6,6'-[(3,3'-Di-t-butyl-5,5'-dimethoxy-1,1'-biphenyl-2,2'-diyl)bis(oxy)]bis(dibenzo[d,f][1,3,2]dioxaphosphepin)hemiethylacetateadduct Usage And Synthesis

Reactions

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.
