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.
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. The arenes have the formula C n H n, substituted derivatives (for example C n (CH 3) n) and heterocyclic derivatives (for ...
An increase in solvent polarity decreases the rates of reactions where there is less charge in the activated complex in comparison to the starting materials; A change in solvent polarity will have little or no effect on the rates of reaction when there is little or no difference in charge between the reactants and the activated complex.

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 section 5.5.5 of his book, Allen [4] compares the reaction field with other methods, focusing on the simulation of the Stockmayer system (the simplest model for a dipolar fluid, such as water). The work of Adams, et al. (1979) showed that the reaction field produces results with thermodynamic quantities (volume, pressure and temperature ...
Yalkowsky’s model utilizes the algebraic mixing rule or log-linear model: logX m = ƒ 1 logX 1 + ƒ 2 logX 2. Where X m is the mole fraction solubility of the solute, X 1 and X 2 denote the mole fraction solubility in neat cosolvent and water. While this model is only correlative in nature, further analysis allows for the creation of a ...
The S N 1 reaction is performed through a stable carbocation intermediate, the more nucleophilic solvent can stabilize the carbocation better, thus the rate constant of the reaction could be larger. Since there’s no sharp line between the S N 1 and S N 2 reaction , a reaction that goes through S N 1 mechanism more is preferred to achieve a ...
