Acetylferrocene is the organoiron compound with the formula (C 5 H 5)Fe(C 5 H 4 COCH 3). It consists of ferrocene substituted by an acetyl group on one of the cyclopentadienyl rings. It is an orange, air-stable solid that is soluble in organic solvents.
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.
A famous example of this type of complex is ferrocene (FeCp 2), which has many analogues for other metals, such as chromocene (CrCp 2), cobaltocene (CoCp 2), and nickelocene (NiCp 2). When the Cp rings are mutually parallel the compound is known as a sandwich complex. This area of organometallic chemistry was first developed in
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]
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
A QRE with ferrocene or another internal standard, such as cobaltocene or decamethylferrocene, referenced back to ferrocene is ideal for nonaqueous work. Since the early 1960s ferrocene has been gaining acceptance as the standard reference for nonaqueous work for a number of reasons, and in 1984, IUPAC recommended ferrocene (0/1+) as a standard ...
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 ...
Ferrocene contains two η 5-cyclopentadienyl ligands. In coordination chemistry, hapticity is the coordination of a ligand to a metal center via an uninterrupted and contiguous series of atoms. [1] The hapticity of a ligand is described with the Greek letter η ('eta'). For example, η 2 describes a ligand that coordinates through 2 contiguous ...
