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.
Density: 1.014 g/mL Melting point: 81 to 83 °C (178 to 181 °F; 354 to 356 K) [1] ... Acetylferrocene is prepared by Friedel-Crafts acylation of ferrocene, ...
1,1 ′-Bis(diphenylphosphino)ferrocene, commonly abbreviated dppf, is an organophosphorus compound commonly used as a ligand in homogeneous catalysis. It contains a ferrocene moiety in its backbone, and is related to other bridged diphosphines such as 1,2-bis(diphenylphosphino)ethane (dppe).
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 the 1950s.
Nozaki’s ferrocene derivative provided products that were only 86% optically pure. Ugi, et al. improved the stereoselectivity by using [1-(dimethylamino)ethyl]-ferrocene, providing products that had an optical purity >95%. The utility of Ugi’s amine in forming ligands for asymmetric catalysis was first reported in 1974 by Kumada, et al. [6]
Cyclopentadienyl magnesium bromide undergoes a complex reaction with iron(III) chloride, resulting in ferrocene: [31] 3 C 5 H 5 MgBr + FeCl 3 → Fe(C 5 H 5) 2 + 1/n (C 5 H 5) n + 3 MgBrCl. This conversion, although not of practical value, was important in the history of organometallic chemistry where ferrocene is emblematic of the field. [32]
Density: 1.256 g/mL Melting point: 81 to 86 °C (178 to 187 °F; 354 to 359 K) ... It is a derivative of ferrocene containing an ethyl group on one of the two ...
Liquid water has a density of approximately 1 g/cm 3 (1 g/mL). Thus 100 mL of water is equal to approximately 100 g. Thus 100 mL of water is equal to approximately 100 g. Therefore, a solution with 1 g of solute dissolved in final volume of 100 mL aqueous solution may also be considered 1% m/m (1 g solute in 99 g water).
