Iron(III)-catalyzed chlorination of activated arenes [PDF]
, 2017 A general and regioselective method for the chlorination of activated arenes has been developed. The transformation uses iron(III) triflimide as a powerful Lewis acid for the activation of N-chlorosuccinimide and the subsequent chlorination of a wide ...

Decarboxylative Halogenation of Organic Compounds
Chemical Reviews, 2020 Decarboxylative halogenation, or halodecarboxylation, represents one of the fundamental key methods for the synthesis of ubiquitous organic halides. The method is based on conversion of carboxylic acids to the corresponding organic halides via selective ...

Synthesis and spectrometric study of some nucleophilic reactions of the antiepileptic molecule; 5,5-diphenyl imidazolidine-2,4-dione. [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2018 New reaction routs were performed for the compound 5,5-diphenyl 2,4-imidazolidinedione (I) to give derivatives (II – VII). These reactions include acylation, halogenation, reduction, and nucleophilic substitutions. Most of the derivatives showed variable

Nontargeted biomonitoring of halogenated organic compounds in two ecotypes of bottlenose dolphins (Tursiops truncatus) from the Southern California Bight. [PDF]
, 2015 Targeted environmental monitoring reveals contamination by known chemicals, but may exclude potentially pervasive but unknown compounds. Marine mammals are sentinels of persistent and bioaccumulative contaminants due to their longevity and high trophic ...

Asymmetric synthesis of gonytolide A: strategic use of an aryl halide blocking group for oxidative coupling [PDF]
, 2018 The first synthesis of the chromanone lactone dimer gonytolide A has been achieved employing vanadium(V)-mediated oxidative coupling of the monomer gonytolide C. An o-bromine blocking group strategy was employed to favor para- para coupling and to enable

Synthesis and Characterization of Mixed Methyl/Allyl Monolayers on Si(111) [PDF]
, 2010 The formation of mixed methyl/allyl monolayers has been accomplished through a two-step halogenation/alkylation reaction on Si(111) surfaces. The total coverage of alkylated Si, the surface recombination velocities, and the degree of surface oxidation as
