| Outline of Final Research Achievements |
From the viewpoint of green chemistry, the use of abundant and non-toxic water has attracted attention, and reaction control technology using aqueous solutions has advanced. For better reaction design, detailed knowledge of how the reaction proceeds in an aqueous solution and the role played by water is required, but existing experimental methods have limitations. In this research, we have clarified the detailed reaction mechanism and the role played by water, targeting organic reactions in high-temperature water using computational chemistry techniques. Through this research, we have established a novel free energy calculation technique for reactions in solution using multi-scale molecular dynamics and first-principles molecular dynamics methods.
