So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Guthardt, Robin; Mellin, Johanna; Bruhn, Clemens; Siemeling, Ulrich researched the compound: 1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene( cas:141556-42-5 ).COA of Formula: C21H24N2.They published the article 《1,1′-Ferrocenylene-Bridged Bis(N-Heterocyclic Olefin) Derivatives》 about this compound( cas:141556-42-5 ) in European Journal of Inorganic Chemistry. Keywords: crystal structure mol ferrocenyl heterocyclic olefin derivative preparation electrochem; ferrocene heterocyclic olefin dimesitylimidazolinylidene diisopropylphenylimidazolinylidene preparation diastereoisomer structure. We’ll tell you more about this compound (cas:141556-42-5).
The 1,1′-ferrocenylene (fc)-bridged bis(N-heterocyclic olefin) compounds (IMes:CH)2fc (1, IMes = 1,3-dimesitylimidazolin-2-ylidene) and (IPr:CH)2fc (2, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) were synthesized from (ICH2)2fc (3) and the resp. N-heterocyclic carbene IMes or IPr. Ligand substitution reactions of 1 and 2 with [BH3(THF)] afforded the complexes [1(BH3)2] and [2(BH3)2] as mixtures of the rac- and meso-diastereomers. The new ferrocene derivatives 1-3 and the complexes meso-[1(BH3)2], rac-[1(BH3)2] and rac-[2(BH3)2] were structurally characterized by single-crystal x-ray diffraction. 1 And 2 represent a new class of ferrocene-based, and hence redox-active, bidentate ligands. The presence of three redox-active moieties, viz. the ferrocene unit and the two NHO units, is reflected by three consecutive oxidations according to an electrochem. investigation exemplarily performed with 2 by cyclic voltammetry.
This literature about this compound(141556-42-5)COA of Formula: C21H24N2has given us a lot of inspiration, and I hope that the research on this compound(1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene) can be further advanced. Maybe we can get more compounds in a similar way.
