摘要：

Ligand substitution reaction of a diastereomerically pure [sexi(quinoxaline-2,3-diyl)]PdBrP2* (P-* = [(S)-2-methylbutyr](2)PPh) at -78 OC produced an enantiomerically pure [sexi(quinoxaline-2,3-diyl)]palladium(II) complex having no chiral auxiliary but just a single chirality of secondary helical structure, which could successfully induce the screw-sense selective self-propelling polymerization of 1,2-diisocyanoarenes.
