===As a ligand scaffold===
Chiral ferrocenyl [[phosphine]]s are employed as ligands for transition-metal catalyzed reactions. Some of them have found industrial applications in the synthesis of pharmaceuticals and agrochemicals. For example, the [[diphosphines|diphosphine]] [[1,1'-bis(diphenylphosphino)ferrocene|1,1′-bis(diphenylphosphino)ferrocene]] (dppf) is a valuable ligand for [[palladium]]-[[coupling reaction]]s.


===As an [[NMR]] standard===
Ferrocene may be used as an NMR standard when doing quantitative NMR, as all of its ten protons are chemically equivalent, it is non-volatile, and is soluble in many organic solvents. In [[Deuterated chloroform|CDCl<sub>3</sub>]], it shows a large singlet located at 4.15 ppm. <ref>https://www.chemicalbook.com/SpectrumEN_102-54-5_1HNMR.htm The NMR of ferrocene</ref>⏎

==Derivatives and variations==
Ferrocene analogues can be prepared with variants of cyclopentadienyl. For example, bis[[indene|indenyliron]] and bisfluorenyliron.<ref name=Stepnicka/>
