Development of Innovative Synthetic Reactions Using Group 7 Metals as Catalysts, Reagents, or Probes

铼在有机合成中不是常用元素。 通过这些研究，我们试图阐明金属的特性，特别是未知的和有用的有机合成反应性。 我们发现了以下合成反应，通过使用配合物作为探针。 (1)路易斯酸催化的含硫配合物反应。 (2)基于C（sp2）-H键活化的反应。 (3)基于羰基和-碳之间的C-C键断裂的反应与双金属络合物。 (4)通过激活邻近位置的杂原子-氢键和C-H键形成杂原子-碳键。 (5)新型C-C键断裂反应的催化剂，由其他过渡金属，而不是钯。

Rhenium is not a popular element in organic synthesis. Through this research, we tried to clarify the features of the metal, especially unknown and useful reactivities for organic synthesis. We have found the following synthetic reactions by using rhenium complexes as probes. (1) Lewis-acid catalyzed reactions with rhenium complexes. (2) Reactions based on the C(sp2)-H bond activation with rhenium complexes. (3) Reactions based on the C-C bond cleavage between carbonyl and -carbons with rhenium complexes. (4) Formation of heteroatom-carbon bonds by activation of heteroatom-hydrogen and C-H bonds at proximity positions. (5) Novel C-C bond cleavage reactions catalyzed by other transition metals than rhenium.
