Access to Planar Chiral Ferrocenes via N-Heterocyclic Carbene-Catalyzed Enantioselective Desymmetrization Reactions was written by Lv, Xiaokang;Xu, Jun;Sun, Cuiyun;Su, Fen;Cai, Yuanlin;Jin, Zhichao;Chi, Yonggui Robin. And the article was included in ACS Catalysis in 2022.Application of 28322-40-9 This article mentions the following:
Ferrocene-derived dicarbaldehydes bearing pro-chiral planes are desymmetrized under the catalysis of chiral N-heterocyclic carbene organic catalysts. The reaction features selective activation and reaction of one of the aldehyde moieties of the ferrocene derivative while leaving the other aldehyde unit untouched. The authors’ reaction affords enantiomerically enriched planar chiral ferrocene products obtained that are amenable for further transformations. Preliminary application studies show encouraging results when the authors’ products are explored for catalysis in chem. synthesis and for antimicrobial utilities in pesticide development. In the experiment, the researchers used many compounds, for example, Isopentyltriphenylphosphonium bromide (cas: 28322-40-9Application of 28322-40-9).
Isopentyltriphenylphosphonium bromide (cas: 28322-40-9) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Application of 28322-40-9
