Oxidative Chlorination of Aromatic Compounds in Aqueous Media
An efficient method for the synthesis of chlorinated arenes is disclosed. The method involves the use of NaClO3 as oxidant and HCl as chlorinating agent in aqueous medium under mild conditions to chlorinate the aromatic compounds in good to excellent yields (75-96%). The reagent system is efficient, organic solvent-free and easy to handle.
متن کاملRegioselective Iodination of Chlorinated Aromatic Compounds Using Silver Salts.
The iodination of chlorinated aromatic compounds using Ag(2)SO(4)/I(2), AgSbF(6)/I(2), AgBF(4)/I(2) and AgPF(6)/I(2) offers access to iodoarenes that are valuable intermediates in organic synthesis. Specifically, iodination of phenols, anisoles and anilines with a 3,5-dichloro substitution pattern preferentially yielded the ortho, para and para iodinated product, respectively. In the case of ch...
متن کاملMiscibility Gaps in Fused Salts
The two families of systems formed by silver halides with alkali Chromates and tungstates have been systematically investigated in order to bring into evidence possible demixing phenomena. It has been found that silver chloride demixes with lithium Chromate and tungstate and with sodium tungstate; silver bromide demixes with lithium and sodium Chromates and tungstates; silver iodide demixes wit...
متن کاملCyclobutene - Fused Aromatic Molecules
The Diels-Alder cycloaddition of dimethyl-1 ,2-cyclobutenedicarboxylate to a 1,3-diene results in the formation of an adduct which can subsequently be decarboxylated and dehydrogenated to provide a cyclobutene-fused benzenoid system. The use of · appropriate dienes has led to the preparation of a series of paraand metabis-annelated benzenes. Variations in the 1H and C NMR and in the UV spectra ...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
