Regiochemical control of the catalytic asymmetric hydroboration of 1,2-diarylalkenes.
The hydroboration of stilbenes and related disubstituted alkenes catalysed by QUINAP complexes may proceed with high enantio- and regioselectivity; rhodium and iridium catalysts give the same product regioisomer but opposite enantiomers.
