The binol ligand has been used extensively in the synthesis of lanthanoid complexes.
These compounds are typically bi-metallic, containing alkali metal ions (M) exempli-
fied by the formula [M
3
Ln(binaphthoxide)
3
].

,
264
They can be used as catalysts in a
wide variety of important organic transformations.
265
Heppert and co-workers have extensively investigated the titanium coordination
chemistry of binol type ligands.
47
The use of chloride compounds for carrying out
enantioselective Diels - Alder reactions has also been evaluated.
