摘要

Pentamethylcyclopentadienide (Me 5 C 5 − , Cp ∗− ) has been used as a ligand of transition metal complexes for 40 years. 1, 1a and 1b Although Cp ∗− has unique properties, such as six-electron donation and steric bulkiness by the five methyl groups on the five-membered ring, it has not been used for other purposes. Then we have been exploring applications of Cp ∗− as a reagent in organic synthesis. 2, 2a, 2b, 2c, 2d and 2e Now, we have been ...
