BINAPHOS-type ligands

Second generation BINAPHOS-type ligands have been developed recently. Placing 3-methoxy substituents on the aryl phosphine unit furnishes a catalyst which allows for an enantioselective hydroformylation of vinylfurans (Scheme 19) [68]. [Pg.159]

In addition to a-olefins, p-/-butylstyrene can be used as a comonomer for the isotactic specific copolymerization with carbon monoxide with chiral induction [32], Whereas bipyridyl as ligand gives a syndiotactic polymer, the Pd-catalyzed polymerization with ligand 11 leads to a polymer with isotacticity of over 98% and high optical activity ([ ]D -536° (in CH2C12)) [33, 34]. The BINAPHOS catalyst described above is also effective in this type of copolymerization [25],... [Pg.762]
