Abstract

Abstract Preparation of new water-soluble derivatives of 5-nitro-2-furan and 5-nitro-2- thiophene from 2-bromo-5-nitrofuran (Ia) or 2-bromo-5-nitrothiophene (Ib) and trimethylamine is described. The trimethylammonium derivatives IIa, IIb react with the azide or cyanide anion in water to afford azides IVa, IVb or nitriles Va, Vb of 5-nitro-2-furan or 5- nitro-2-thiophene. The reactivity of these azides with dimethyl 2-butinedioate and triphenyl ...
