| Outline of Final Research Achievements |
A cyclic aluminum compound was found to be a precursor of a nucleophilic Al-centered anion. After the isolation of the Al anion, its structure, reactivity, and spectroscopic properties were disclosed. As a part of the research about boryl anion, synthetic study on C,N-substituted boryl anion and synthesis of multiple-bonded main group element compounds having boryl substituents were investigated. On the other hand, (o-tol)2B-B(o-tol)2 was synthesized as a new diborane(4) compound. The remarkable reactivity of (o-tol)2B-B(o-tol)2 toward H2, CO, and N=N double bond was also revealed with a support of DFT calculations providing mechanistic insights. Throughout the research, we could demonstrate the characteristics of the vacant orbital of these compounds providing rare modes of reactions. Therefore, the initial purpose of this research project was well-achieved.
