What is Nitro‐substituted iron(II) tridentate bis(imino)pyridine complexes as high‐temperature catalysts for the production of α‐olefins about?

## Abstract A new series of nitro‐substituted bis(imino)pyridine ligands {2,6‐bis[1‐(2‐methyl‐4‐nitrophenylimino)ethyl]pyridine, 2,6‐bis[1‐(4‐nitrophenylimino)ethyl]pyridine, (1‐{6‐[1‐(4‐nitro‐phenylimino)‐ethyl]‐pyridin‐2‐yl}‐ethylidene)‐(2,4,6‐trimethyl‐phenyl)‐amine, and 2,6‐bis[1‐(2‐methyl‐3‐nitrophenylimino)ethyl]pyridine} and their corresponding Fe(II) complexes [{__p__‐NO~2~__o__‐MePhNC(Me)PyC(Me)NPh__o__‐ Me__p__‐NO~2~}FeCl~2~ (10), L~2~FeCl~2~ (11), {__m__‐NO~2~__o__‐MePhNC(Me)PyC(Me)NPh__o__‐Me__m__‐NO~2~}FeCl~2~ (12), and {__p__‐NO~2~PhNC(Me)PyC(Me)NMes}FeCl~2~ (14)] were synthesized. According to X‐ray analysis, there were shortenings of the axial FeN bond lengths (up to 0.014 Å) in __para__‐nitro‐substituted complex 10 and (up to 0.015 Å) in __meta__‐nitro‐substituted complex 12 versus the Fe(II) complex without nitro groups [{__o__‐MePhNC(Me)PyC(Me)NPh__o__‐Me}FeCl~2~ (1)]. Complexes 10, 12, and 14 afforded very active catalysts for the production of α‐olefins and were more temperature‐stable and had longer lifetimes than parent non‐nitro‐substituted Fe(II) complex 1. The reaction between FeCl~2~ and a sterically less hindered ligan
