Polyphenylalkene derivatives
Q 0740
Asymmetric Kumada—Corriu Cross-Coupling Reaction with Pd2(dba)3 and an
Axially Chiral Mimetic-Type Ligand Catalyst. — The chiral piperidine (Ia)
09- 083 N—Ar
is an efficient ligand for the chemo- and enantioselective Kumada—Corriu cross-coupling of β-bromostyrene derivatives. The degree of enantioselectivity is strongly
dependent on the structure of the ligand as well as on the nature of the metal complex.
The electronic nature of the starting styrene affects the yield. — (HORIBE, H.;
