Abstract: The reactivity of l,l-dichloro(resp. l,l-dibromo)-2-(5-nitro-2-furyl)ethylene and analogous thiophene derivatives in the reaction with sodium methanolate was assessed by kinetic studies. Based on the obtained rate constants k₁ and k₂, isolated intermediates as well as on spectral studies the reaction mechanism of the exchange of one or both halogen atoms is discussed.
