Indene(Cas 95-13-6) Usage

Chemical Description |
Indene is a bicyclic aromatic hydrocarbon with the chemical formula C9H8. |
|
Synthesis Reference(s) |
Tetrahedron Letters, 18, p. 49, 1977 DOI: 10.1016/S0040-4039(01)92547-X |
|
Reactivity Profile |
Indene is combustible (flash point between 140°F and 200°F). Polymerizes and oxidizes on standing in the air. This reaction is accelerated by heating, acids, and catalysts, including peroxides. Has exploded during nitration with a mixture of H2SO4 and HNO3. |
|
Health Hazard |
Indene is expected to be an irritant of the mucous membranes. |
|
Purification Methods |
Shake indene with 6M HCl for 24hours (to remove basic nitrogenous material), then reflux it with 40% NaOH for 2hours (to remove benzonitrile). Fractionally distil, then fractionally crystallise it by partial freezing. The higher-melting portion is converted to its sodium salt by adding a quarter of its weight of sodamide under nitrogen and stirring for 3hours at 120o. Unreacted organic material is distilled off at 120o/1mm. The sodium salts are hydrolysed with water, and the organic fraction is separated by steam disillation, followed by fractional distillation. Before use, the distillate is passed, under nitrogen, through a column of activated silica gel. It turns yellow in air as it readily oxidizes and polymerises.

General Description |
Indene is a key intermediate in the synthesis of 2-aryl indenones through gold-catalyzed cycloisomerization/aerobic oxidation cascades, as demonstrated in the transformation of 1,5-enynes. It also serves as a foundational structure in the development of fluorinated cyclopentadienyl and indenyl ligands, which are studied for their catalytic properties in olefin polymerization. The reactivity and stability of these indenyl-based ligands are influenced by their substituents, highlighting their versatility in organometallic chemistry and materials science. |
