Quinoline Pyridine(Imine) Iron Complexes as Catalysts for the 1,4-Hydrovinylation of 1,3-Dienes

Abstract

The synthesis, characterization, and stoichiometric reactivity of a series of quinoline pyridine(imine) ( R(R') Q (R") PI) (R = 2,6-Me, 2,6-iPr or 2,4,6-Cy; R' = H or Cl, R″ = H or tBu) iron dichloride complexes is described. Treatment of (QPI)FeCl 2 with two equivalents of methyl lithium furnished two examples of the corresponding (QPI)FeCH 3 complexes. The molecular structures were established by X-ray diffraction, and the electronic structures were studied by magnetometry, 57
