Hindered diarylether and diarylsulfone bisphosphine ligands: atropisomerism and palladium complexes

Phosphines and bisphosphines derived from hindered ortho-substituted diaryl ethers and diarylsulfones by lithiation are, with appropriate substitution patterns, resolvable atropisomeric ligands which form crystalline complexes with palladium dichloride.

Appropriately substituted bisphosphinyldiaryl ethers are resolvable atropisomeric ligands which form stable wide bite angle complexes with Pd.Figure optionsDownload as PowerPoint slide
