Amidine Dications as Superelectrophiles
2-Dimethylalkylammonium pyridinium and 2-dimethylalkylammonium pyrimidinium ditriflate salts are very powerful methylating agents toward phosphorus (triphenylphosphine) and nitrogen (triethylamine) nucleophiles. In competition experiments with triethylamine as nucleophile, these N-methyl disalts are more reactive methylating agents than dimethyl sulfate. Reaction of the pyridinium dications wit...
متن کاملAntioxidant Activity of some Amidine Derivatives
Three amidines, N, N’-Diphénylbenzamidine (1), N-Cyclohexyl-N’-phényl-octamidine (2), N, N’diphényldodécamidine (3), were synthesized and investigated for their antioxidant activity using 2, 2-diphenyl-1picrylhydrazyl (DPPH) radical scavenging, ferric reducing antioxidant power (FRAP) and β-carotene/linoleic acid assays. The results indicated that amidines tested possess good antioxidant activi...
متن کاملAmidine: Structure, Reactivity and Complexation Behaviour
The present review discuss about the structure, reactivity of various amidines. The complexation behavior of amidine especially aryl benzamidine with different metal ions has been discussed. This review article is useful for inorganic and bioinorganic chemist.
متن کاملAmidine Dications: Isolation and [Fe]-Hydrogenase-Related Hydrogenation
This communication demonstrates the preparation, isolation, and full characterization of superelectrophilic salts based on amidine dications in organic solvent, as their triflate salts. These dications are highly activated toward regiospecific reaction with hydrogen gas under mild conditions in the presence of a metal catalyst (Pd/C), mimicking the behavior of the natural substrate, N(5),N(10)-...
متن کاملAntimicrobial lexitropsins containing amide, amidine, and alkene linking groups.
The synthesis and properties of 80 short minor groove binders related to distamycin and the thiazotropsins are described. The design of the compounds was principally predicated upon increased affinity arising from hydrophobic interactions between minor groove binders and DNA. The introduction of hydrophobic aromatic head groups, including quinolyl and benzoyl derivatives, and of alkenes as link...
