gives a mixture of all four possible isomers. Sodium methoxide was reacted with these isomers to determine the configuration about the carbon–carbon doublebond for each. The Z-isomers reacted with sodium methoxide to give the corresponding alkyne by elimination whereas the E-isomers gave the substitution product. The configuration about the carbon–nitrogendoublebond was determined from the 1H NMR chemical

Abstract A simple route is described for the synthesis of E and Z 3‐chloro‐2‐propenamides (4a‐e), esters (3a) and acids (2a‐c) by the reaction of 2,3‐acetylenic acids with oxalyl chloride in DMF followed by treatment of the corresponding 3‐chloro‐2‐propenoyl chloride derivative with amines, alcohol and water.
