2,2'-Disubstituted F12binaphthyl derivatives: stannanes, boranes, and (R)-F12BINOL.
2,2'-Distannyl derivatives of dodecafluorobinaphthalene are converted to a novel D2 symmetric borane dimer, which can be oxidized to (+)-F12BINOL; resolution using (S)-acetoxypropanoyl chloride affords enantiopure material.
