Acetylferrocene is prepared by Friedel-Crafts acylation of ferrocene, usually with acetic anhydride (Ac 2 O): . Fe(C 5 H 5) 2 + Ac 2 O → (C 5 H 5)Fe(C 5 H 4 Ac) + HOAc. The experiment is often conducted in the instructional laboratory to illustrate acylation as well as chromatographic separations.
Ferrocenecarboxaldehyde behaves like other aldehydes in terms of its reactivity, the main difference is that it is electroactive. Its basicity is indicated by the solubility of the compound in hydrochloric acid.
"NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [ 1 ] and revised several times since then, it defines the " Safety Square " or " Fire Diamond " which is used to ...
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.
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
The National Fire Protection Association (NFPA) is a U.S.-based international nonprofit organization devoted to eliminating death, injury, property, and economic loss due to fire, electrical, and related hazards.
The publication Life Safety Code, known as NFPA 101, is a consensus standard widely adopted in the United States. [according to whom?] It is administered, trademarked, copyrighted, and published by the National Fire Protection Association and, like many NFPA documents, is systematically revised on a three-year cycle.
It can be synthesized by the Clemmensen reduction of acetylferrocene. [2] References This page was last ...
