Ortho-substituted iodobenzenes as novel organocatalysts for bromination of alkenes.
Suitably ortho-substituted iodobenzenes act as organocatalysts for the transfer of electrophilic bromine from N-bromosuccinimide to alkenes via the intermediacy of bromoiodinanes.
متن کاملBromination of Alkenes
The two most common halogenation reactions are chlorination and bromination. The addition of these halogens to alkenes yields 1,2-dihalides. Chlorinations reactions are used to synthesize over 6 million tons per year of ethylene dichloride (1,2-dichloroethane) for use as a solvent and for subsequent polymerization to produce poly(vinylchloride) known more commonly as PVC which is used for plumb...
متن کاملDiagnosis of Tuberculosis: Novel Laboratory Methods
Despite advances in medical sciences in recent years, tuberculosis remains a worldwide health problem. Although there are many laboratory methods to accelerate the diagnosis, a delay in the definitive diagnosis of the disease is still a major clinical problem. Due to the slow growth of the causative agent, (Mycobacterium tuberculosis), isolation, identification, and other clinically important m...
متن کاملSelective Mono Bromination of 1,4-Dihydropyridines
2-monobromomethyl 1,4-dihydropyridines is selectively synthesized by bromination of the parent compound by 1.1 equivalents of pyridinium bromide perbromide in dichloromethane/pyridine at -20 °C. The same reagent in dichloromethane at 0 °C produce the 2,6-bis(bromomethyl) 1,4-dihydropyridines.
