| Outline of Final Research Achievements |
Diene-iron complexes are known as a high stability and low toxicity compound. The tricarbonyl iron fragment is mainly exploited as a protecting group or as a stereo-directing group. In many reactions using diene iron complexes, the diene moiety does not participate in organic transformations.
In this study, we tried to develop the new synthetic method of a diacyliron complexe from a cyclic diene-iron complexe bearing a substituent at C1. In this method, the cyclic diene-iron complex was treated with a strong base such as LDA in the presence of a phosphorus ligand. We focused on the synthesis of the diacyliron complex with high crystallinity for X-ray analysis. We found that the complexation proceeded smoothly at 50 degree Celsius under ultrasonic irradiation.
