The helical pentamer 1, active in polymerizations , was obtained from the appropriate 1,2‐dgaiisocyanoarene and the chiral Pd complex trans ‐[PdBr(CH 3 )L 2 * ]. With diastereomerically pure 1 as the polymerization initiator helical polyquinoxalinediyls can be prepared enantioselectively from 1,2‐diisocyanoarene. L * = PPh[( S )‐2‐methylbutyl] 2 .
