Isocyanide insertion reaction in alkylcomplexes of iron: A dihaptoiminoacyl derivative of iron (II) (original) (raw)

Abstract

The dihaptoiminoacyI complex [Fe(C0)2 (PMe3)2(q2-CMe=N-CMe3)]+ I-was obtained by reaction of [Fe(CO)z(PMes)zMeI] and tertbutylisocyanide. The structure of the complex was determined by an X-ray structure analysis.

What distinguishes isocyanide insertion from carbon monoxide insertion?add

The study reveals that isocyanide insertion prevails in cases where both options exist, despite its higher activation energy compared to CO insertion.

How does the reaction mechanism involve acid catalysis during isocyanide insertion?add

The research indicates that acid catalysis facilitates the formation of a stable dihapto structure as an insertion intermediate during isocyanide reactions.

What structural characteristics define the dihaptoiminoacyl complexes described?add

Dihaptoiminoacyl complexes are characterized by their unique nitrogen coordination and were synthesized from iron (II) complexes in the report.

What methods were used to analyze the synthesized complexes' structures?add

Elemental analyses and crystallographic data have been used to confirm the proposed formulations and structural characteristics of the synthesized complexes.

When was the described iron (II) complex synthesized, and what was its precursor?add

The iron (II) complex was synthesized from [Fe(CO)2(PMe3)2MeI] and tert-butylisocyanide in benzene, resulting in a new complex in a molar ratio of 1:1.
