| Outline of Final Research Achievements |
In this work, we investigated synthesis, structures and reactivity of the Ga-containing 5-membered cyclic diene, gallacyclopentadienes 1. Halogeno- and transition metal-substituted gallacyclopentadienes were synthesized by the reaction of RGaCl2 with zirconacyclopentadienes. The reactions of 1 with sterically less hindered Lewis base afforded the mixtures of the Lewis base adducts of 1 and 5,10-digallacyclodecatetraene derivatives, the latter of which would be formed via dimerization of 1 and rearrangement. Similar ring-expansion also occurred in the reaction of 1 with a precursor of the 12-electron transition metal complex.
