Webmethyl ketone moiety had to be transformed to a methyl ester, which was accomplished by using the Lieben haloform reaction. The aqueous solution of sodium hypobromite (prepared by adding Br2 to sodium hydroxide) was slowly added to the solution of substrate in dioxane. The resulting carboxylate salt was converted to the methyl ester using The haloform reaction is one of the oldest organic reactions known. In 1822, Georges-Simon Serullas added potassium metal to a solution of iodine in ethanol and water to form potassium formate and iodoform, called in the language of that time hydroiodide of carbon. In 1832, Justus von Liebig reported the reaction of chloral with calcium hydroxide to form chloroform and calcium formate. The reaction was rediscovered by Adolf Lieben in 1870. The iodoform test is also called … launching issues on outlook
