ferrocene
Ferrocene is an organometallic chemistry, organometallic compound with the formula . The molecule is a Cyclopentadienyl complex, complex consisting of two Cyclopentadienyl anion, cyclopentadienyl rings sandwiching a central iron atom. It is an o ...
. It is a yellow solid that is soluble in aqueous base. The 1,1' part of its name refers to the location of the carboxylic acid groups on separate rings.
It can be prepared by hydrolysis of its diesters (R = Me, Et), which in turn are obtained by treatment of
ferrous chloride with the sodium salt of the carboxyester of cyclopentadienide . Ferrocenedicarboxylic acid is the precursor to many derivatives such as the di
