The invention relates to synthesis and application of 2,3-hydrocarbyl substituted diester succinate. At a low temperature, carboxylic ester and strong base LDA (Lithium Diisopropylamide) react to form alkenyl alkoxide which is oxidized and coupled by carbon tetrachloride to prepare 2,3-hydrocarbyl substituted diester succinate. Liquid nitrogen has the gas protecting and refrigerating functions by a novel method of introducing liquid nitrogen to a reaction system to perform direct refrigeration. The direct refrigerating method has the advantages of energy conservation, easiness in control of reaction temperature, and replacement of inertial protective gas. The 2,3-hydrocarbyl substituted diester succinate can be used as an electron donor of a polypropylene catalyst.
