Методика

A mixture of 2,5-dinitrophenol (4.0 g), potassium carbonate (4.6 g), NMP (40 mL) and 1,4-dibromo-2-butene (14.0 g) is heated to 45° C. for 2 hr. Extraction in the normal fashion and Kugelrohr distillation of the excess dibromide (0.1 mm Hg, 80° C.) gives 1-bromo-4-(2,5-dinitrophenyloxy)but-2-ene (mp 81-83° C.).
