| Research Abstract |
I have been working on chemistry of transition metal complexes having the Cp'-P ligand. The Cp'-P ligand has both a cyclopentadienyl derivatives and a tertiary phosphine group connected by an appropriate spacer. The complexes having Cp'-P ligand are expected to show the combination character of cyclopentadienyl complexes and phosphino complexes. Addition of them, we can disclose an interesting behavior of the Cp'-P ligand through our research.
In this project, I can find some interesting results obtained by using the Cp'-P ligand. Main points are shown the followings.
First, I have prepared the several kinds of Cp'-P ligand and examined their characters. We can find out that the combination of planar chirality and stereogenic center on the substituent was very effective for controlling the chirality on Rh center.
Second, we have obtain experimental evidence for migration of an alkyl group in migratory insertion and retro-Migratory Insertion by using the three-legged piano-stool rhodium Complex having Cp'-P Ligand.
Third, as an application to organic synthesis, I have developed stereo- and regio selective acylmethylation of alkynes mediated by the Cp'-P Rh complexes.
