摘要: 本文应用分子模拟途径研究了系列反应物丙烯基羟基乙烯酮二硫代乙缩醛在有、无分子筛催化条件下Thio-Claisen重排。我们证实Sreekumar等人实验在有、无分子筛催化条件下的Thio-Claisen重排结果可分别通过分子筛反应物之间相互作用的能学和反应物的空间能计算得到合理解释。本文的方法能成功地识别一个给定Thio-Claisen重排在有、无分子筛催化条件下的优化产物。 |

Abstract: Molecular simulation is applied to investigate the Thio Claisen rearrangement of various s-Allyl-hydroxy ketene dithioesters with and without zeolites catalysts. We show that the experimental results of Sreekumar et al with and without zeoiltes can be rationalized in terms of the energetics of the zeolite reactant interactions and the steric energy of the reactants, respectively. The procedures used can successfully identify optimum products for a given Thio-Claisen rearrangement with and without zeolites catalysts. |
