In 1951, German theoretical chemist Ernst Otto Fischer and British chemist Sir Geoffrey Wilkinson independently discovered the sandwich structure of the compound ferrocene. |
Sodium methylate and then cyclopentadiene are added, and ferrocene ultimately precipitates out of the solution. |
All ferrocenium salts were prepared via a ligand exchange reaction between one ring of ferrocene and arene, according to the following procedures. |
Among its organometallic compounds is ferrocene, the first sandwich compound discovered. |
In 1951 Fischer read about a newly developed synthetic compound called ferrocene whose structure was unknown. |
The cathode is a viologen, while the anode is a ferrocene, phenazine, or thianthren. |
