2-Butene, 1,4-dibromo- → 2-Butene-1,4-diol diacetate

Participants

Reaction Steps

After adding 1 g of 1,4-dibromo-2-butene (available from Sigma-Aldrich Co.) and 3 g of sodium acetate (available from Wako Pure Chemical Industries, Ltd.) into ethanol, reflux was conducted at 80° C. for 1 hour, to obtain 1,4-diacetoxy-2-butene. 1,4-diacetoxy-2-butene was dissolved in 30 ml of ethanol, and 20 ml of an aqueous sodium hydroxide solution (1 mol/l) was added, to synthesize 2-butene-1,4-diol.
