異核鈀鈷雙金屬錯合物催化氨基磺酸酯進行碳-氫鍵氮烯插入及藉由二乙醯氧基碘苯氧化苯基縮醛之研究

Heterobimetallic Palladium-Cobalt Complex Catalyzed C-H Bond Nitrene Insertion of Sulfamate Esters, and Oxidation of Benzylic Acetal by(Diacetoxyiodo)benzene.

指導教授 : 莊敬

摘要


本實驗分為兩部份進行研究探討,第一部分主要研究以氨醯磺酸酯類化合物(六員環、五員環、四員環、縮醛基)當作起始物藉由PdCo(OAc)4催化碳-氫鍵插入胺化反應。也嘗試以環丙烷(radical clock)起始物進行碳-氫鍵插入胺化反應來推測該反應是藉由協同式氮烯插入抑或經由自由基反應機構。 第二部分以二乙醯氧基碘苯氧化苯基縮醛形成類似原酸酯類化合物。

並列摘要


The presenting study can be divided into two parts. The first part of the study of sulfamate esters compound containing (six ring、five ring、four ring and Acetal group) as the starting materials in PdCo(OAc)4 catalyzed C - H amination reaction. Starting material with radical clock (cyclopropyl group) was alse tested in the C - H amination reaction to determine the possibility of radical mechanism. The second part is about using (diacetoxyiodo)benzene an oxidant for the oxidation of phenyl acetal compounds to form orthoesters.
