| dc.description | Manganese(IV)–hydroxo complex, C–H bond activation, Oxygen non-rebound mechanism | - |
| dc.description.abstract | A high-valent manganese–hydroxo complex has been synthesized and characterized using various physicochemical methods such as UV–vis, ESI-MS, IRPD, and DFT calculations. Generally, manganese-oxygen adducts can activate C–H bond through an oxygen non-rebound mechanism where the rate of hydrogen atom transfer (HAT) depends on the strength of C–H bond. Herein, in the formation process of manganese–hydroxo complex, [MnIV(CHDAP–O)(OH)]2+, the C–H bond activation of the 2,6 position in cyclohexyl groups unusally proceeds via an oxygen rebound mechanism, in which HAT is identified as a rate determining step. | - |

| dc.description.alternativeAbstract | 본 논문은 망가니즈 하이드록소 종의 형성 과정에서 일어나는 탄소-수소 결합 활성 메커니즘에 관한 것이다. 망가니즈-활성산소 종이 탄소-수소 결합을 산화시키는 과정에서는 일반적으로 산소가 다시 결합하지 않는 메커니즘으로 진행되는 것으로 알려져 있고 또한 수소원자 전달 과정의 속도는 탄소-수소 결합의 세기에 의존하는 것으로 알려져 있다. 본 논문에서는 망가니즈 하이드록소 종에서 사이클로헥실 그룹의 오소 위치의 수소가 산화되는 메커니즘이 산소 재결합 경로로 진행되는 것을 알아보기 위한 연구를 수행하였고, 수소원자 전달 과정이 속도 결정 단계임을 확인하였다. 본 논문은 망가니즈-활성산소 종들의 탄소-수소 산화반응 메커니즘을 규명하는 연구에 도움을 줄 수 있다. |
