Abstract: | The very reactive cyclopentadienyliron species, (RC5H4)Fe, are relatively easily generated by electrochemical reduction of appropriately substituted and readily available ferrocenes. Thus (MeCOC5H4)Fe has been generated by monoelectronic reduction of (MeCOC5H4)2Fe; it reacts with CO leading, after further reduction, to the acetyl cyclopentadienyldicarbonyliron anion. Reactions of this anion give ring-substituted cyclopentadienyldicarbonyliron derivatives containing the electron-withdrawing MeCO substituent. |
