The results of the reaction show that better regioselectivity is obtained when Cd2+ is used as additive and give stereoselective product when cinchonine is used as chiral additive.Keywords: NaBH4, Regioselective,Stereoselective,Benzoyl acetone,Metal ion

结果发现，不同的金属离子添加剂使反应出现不同的化学选择性，而Cd2+离子对苯甲酰丙酮的还原具有较好的化学选择性，同时在辛可宁存在条件下得到了对映体过量的产物。

From the view of conservation of organic matter, the water body in evaporates basin takes on the character of density stratification; the niederschlag below mascon has high oxidation-reduction potential, which contribute to the conservation of organic matter. From the view of generation of hydrocarbon, bacteria, algae and lithology on the bottom of salt-water basin play important role in generation of hydrocarbon; furthermore, clunch from the redbeds acting as catalyzer, alkali metals making the hydrocarbon mobile.

从油气生成条件看，细菌、藻类及咸水盆地底层的岩性对油气的生成具有重要作用，此外红层中的粘土对烃类的生成起到催化的作用，碱金属可使生成的烃类发生流动；从有机质的保存条件看，蒸发岩盆地水体中具有密度分层的特点，在高密度层以下的沉积物具有强的氧化还原电位，从而使有机质保存下来。
