| Outline of Final Research Achievements |
Most of the organoaluminum compounds contain trivalent aluminum atoms with the formula of AlR3. In contrast, the properties of low-oxidation state aluminum species, Al(II) and Al(I), have not been investigated thoroughly to date. The low-oxidation state aluminum species are generally highly reactive and thus have been proposed only as short-lived, elusive intermediates in several organic reactions. Recent development in main group element chemistry, however, have made its possible to isolate highly reactive low-valent organoaluminum species as bottlable compounds and investigate their reactivity in detail. In this research, the reactivity of organoaluminum species bearing Al-Al bonding towards various unsaturated compounds and dihydrogen was investigated by using "masked dialumenes", which generate highly reactive Al=Al doubly bonded species, dialumenes, under mild conditions.
