Access to Unsymmetric Binaphthols through Oxidative Coupling of Silicon Bisnaphtholates

Michael Schmittel EMAIL logo and Andreas Haeuseler

The oxidative coupling of various symmetric (5 -7) as well as unsymmetric silicon bisnaphtholates (11, 12), initiated by different oxidants (iron(III), cerium(IV), copper(II) or hypervalent iodine), furnishes the corresponding symmetric and unsymmetric binaphthols 13 - 17. The coupling reaction of the substrates follows strictly an intramolecular pathway.
