Phthalocyanine iron alkyls

The reduced alkyl complexes are reoxidized by O2 to the iron(lll) alkyls. The corresponding diamagnetic phthalocyanine iron(ll) alkyl complexes, rFe(Pc)R), were prepared by two-electron reduction of Fe(Pc) by LiAIFl4 to give [Fe(Pc) (actually the Fe(I) phthalocyanine radical anion) followed by reaction with Mel, Etl or i-PrBr. The methyl compound, [Fe(Pc)CHi] was characterized by X-ray crystallography. ...

In 2013, Singh and co-workers also reported an iron(II) phthalocyanine (FePc)-catalyzed /-alkylation of heterocyclic amines (Fq. 31) [129]. In most cases, the reactions of benzyl alcohols could give moderate to excellent yields, but aliphatic alcohols gave only poor yields of the products.
