| Research Abstract |
Although spherand developed by Cram et al in 1985 has been known as the most powerful clathrate toward lithium cation, almost no application has been reported. We developed synthetic routes of spherand because the literature method was inefficient and poorly reproducible, and new series of spherand derivatives were prepared in order to improve the solubility to organic solvents. Newly prepared spherand derivatives with cyclohexyl substituents were applied to stabilize pentacoordinate tin ate complexes. As expected, tin ate complexes became much more stable thermally in the presence of the spherand
