Iron-catalyzed Carbon-carbon Bond Formations And Iodine-catalyzed Disulfidation Of Alkenes

In this thesis, we found that these two coupling reactions can be achieved in the presence of low-cost iron salts and 2,2'-diamino-6,6'-dimethylbiphenyl. Furthermore, an iodine-catalyzed disulfidation reactions of alkenes was developed in this thesis. The thesis includes the following parts:(1) Iron-catalyzed Suzuki-Miyaura coupling reactions of aryl iodides and bromides with arylboronic acids, which using Fe₂O₃ as iron source and 2,2'-diamino-6,6'-dimethylbiphenyl as ligand, has achieved a good result. (2) Iron-catalyzed Mizoroki-Heck reactions of aryl iodides with methyl acrylate and styrene, which using respectively FeCl₃.6H₂O and Fe(acac)₃ as iron source and 2,2'-diamino-6,6'-dimethylbiphenyl as ligand, has achieved a good result. (3) iodine-catalyzed disulfidation of alkenes. We found that the disulfidation of alkenes can be achieved at room temperature with water or 1,2-dichloroethane as the solvent, respectively.
