Ferrocene is an organometallic compound with the formula Fe(C 5 H 5) 2.The molecule is a complex consisting of two cyclopentadienyl rings sandwiching a central iron atom. It is an orange solid with a camphor-like odor that sublimes above room temperature, and is soluble in most organic solvents.
Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s.

Ferrocenophanes, also called ansa ferrocenes (from ansa: handle in greek), are organometallic compounds which are derived from ferrocene. They are a subset of ansa-metallocenes in which the metal is iron. In this compound class, the cyclopentadienyl ligands of the ferrocene are connected by one or more bridging groups. This hinders the rotation ...
Space-filling model of ferrocene, the archetypal sandwich compound. In organometallic chemistry, a sandwich compound is a chemical compound featuring a metal bound by haptic, covalent bonds to two arene (ring) ligands.
Ferrocenecarboxaldehyde, owing to the versatility of the formyl group, is a precursor to many ferrocene-modified compounds. With a Wittig reagent, it converts to vinylferrocene and related derivatives. [5] With primary amines, ferrocenecarboxaldehyde condenses to give imines. The azomethine derivative undergoes 1,3-cycloaddition to C 60. [6]
Rice water is a starchy liquid that results from soaking the grain in water or cooking it in water, Khetarpal explains. Depending on the type of rice, its starch content can range between ~60% to 90%.
When it comes to losing weight, there are no shortage of unproven recommendations to choose from: fad diets like the carnivore diet or GOLO diet; juice cleanses and vitamin injections; plus a host ...
Ferrocene. The first metallocene to be classified was ferrocene, and was discovered simultaneously in 1951 by Kealy and Pauson, [2] and Miller et al. [3] Kealy and Pauson were attempting to synthesize fulvalene through the oxidation of a cyclopentadienyl salt with anhydrous FeCl 3 but obtained instead the substance C 10 H 10 Fe [2] At the same time, Miller et al reported the same iron product ...
