Wp. Deng et al., On the role of planar chirality: a tunable enantioselectivity in palladium-catalyzed allylic alkylation with planar chiral 1,1 '-P,N-ferrocene ligands, CHEM COMMUN, (4), 2000, pp. 285-286
A series of planar chiral 1,1'-P,N-2'-substituted ferrocene ligands 9-12 an
d 16, prepared with diastereopurity > 99:1, have been used to examine the r
ole of planar chirality, and significant effects on enantioselectivity as w
ell as the control of absolute configuration in palladium-catalyzed allylic
alkylation as a model reaction were observed.
