| Research Abstract |
1. We synthesized the first hypervalent hexacoordinate carbon compound (12-C-6) and the structure was confirmed by detailed X-ray analysis.
2. Synthetic methods for Cram's spehrand were improved and new derivatives bearing t-Bu and cyclohexyl substitutents were prepared in order to get more soluble compounds.
3. By use of the newly developed ligand, two stereoisomers of pentacoordinate antimony compounds (stiboranes) were synthesized, isolated, and characterized by X-ray analysis. Kinetic measurements were performed. Based on the calculation of the mechanism, we can conclude that the isomerization proceed by way of the turnstile rotation.
