1,4-Dicyanobenzene Chemical Properties,Usage,Production
Chemical Properties
biege powder
Uses
1,4-dicyanobenzene as a new internal standard in utilizing solid-state infrared intensity methods for the determination of thiocyanate bonding. Used as photosensitizer in [2+2] cycloadditions, nitrile building block.
Synthesis Reference(s)
The Journal of Organic Chemistry, 51, p. 4714, 1986 DOI: 10.1021/jo00374a041
Tetrahedron Letters, 8, p. 759, 1967
Safety Profile
Moderately toxic by ingestion and intraperitoneal routes. An eye irritant. When heated to decomposition it emits toxic fumes of CNand NO,. See also NITRILES.
Purification Methods
Crystallise the dinitrile from EtOH or AcOH, and has m 221.5-222.5o after sublimation. [Beilstein 9 H 846, 9 I 376, 9 II 613, 9 III 4255, 9 IV 3328.]
