Development of New Catalytic Activities of Rhenium Complexes and Their Applications

与其他金属元素相比，合成反应的报道很少。因此，我们开始探索稀土配合物在有机合成中应用的可能性。在这个项目中，我们发现了以下利用Re络合物的特殊特性的反应。(1)基于稀土配合物与C(sp^2)-H键活化的新反应。(2)基于β-酮酸酯与稀土配合物C-C键断裂的新反应。(3)Re催化的β-酮酸酯与烯的立体选择性[3+2]环加成反应。(4)苯酚的区域选择性烷基化反应。(5)锰催化的选择性[2+2+2]环加成反应生成对三苯基

Compared to other metal elements, only a few synthetic reaction have been reported. Therefore, we started to explore the possibility of the use of rhenium complexes in organic synthesis. During this project we have found the following reactions using specific features of rhenium complexes. (1) Novel reactions based on the C(sp^2)-H bond activation with rhenium complexes. (2) Novel reactions based on the C-C bond cleavage of β-keto esters with rhenium complexes. (3) Rhenium catalyzed stereoselective [3+2]cycloaddition between β-keto esters and allenes. (4) Regioselective alkylation of phenols using olefins with a rhenium catalyst. (5) Manganese-catalyzed selective [2+2+2]cycloaddition leading to p-terphenyls
