incorporated in the arylgroup enhanced the catalytic activity from a turnover frequency (TOFmax)=1600 h−1 in the original Ph‐PYA system gradually as more MeO groups were introduced up to a TOFmax=3300 h−1 for a tris(MeO)‐substitutedaryl‐PYA system. The variation of the PYA substitution had only a minor impact on catalytic activity and revealed only a weak trend in the sequence ortho>meta>para. The high activity
