Potassium ethoxide since any transesterification reaction does not result in ester scrambling. Potassium ethoxide is stable, but also both flammable and corrosive. The compound reacts vigorously with water. If the compound comes into contact with damp air, it may lead to the heating and ignition of the solid powder. Keep separated from air, moisture, water, acids, oxidzing agents, and reducing agents. It can also cause severe skin burns. Potassium ethoxide Potassium ethoxide, also known as potassium ethanolate, is an off-white or yellow powder with the chemical formula of CHKO. Potassium ethoxide contains an ethoxide ion, the conjugate base of ethanol, which makes
Sandwich compound Sandwich compound In organometallic chemistry, a sandwich compound is a chemical compound featuring a metal bound by haptic covalent bonds to two arene ligands. The arenes have the formula CH, substituted derivatives (for example C(CH)) and heterocyclic derivatives (for example BCH). Because the metal is usually situated between the two rings, it is said to be "sandwiched". A special class of sandwich complexes are the metallocenes. The term "sandwich compound" was introduced in organometallic nomenclature in the mid-1950s in a report by J. D. Dunitz, L. E. Orgel and R. A. Rich, who confirmed the structure of ferrocene by X-ray
