Tetracyanoethylene Chemical Properties,Uses,Production
Chemical Properties
white to beige-brown crystalline powder, crystals. Tetracyanoethylene [670-54-2], ethenetetracarbonitrile, TCNE, ( NC)2C = C (CN)2, Mr 128.09, mp 197 – 198℃, bp 223℃, n25 D 1.560. The preferred synthetic preparation of TCNE involves the debromination of the KBr complex of dibromomalononitrile. Tetracyanoethylene is a reactive compound that undergoes a variety of reactions including addition, replacement and cyclization. The chemistry of TCNE is exhaustively reviewed in.
Definition
The first member of a class of compounds called cyanocarbons.
Hazard
Hydrolyzes in moist air to hydrogen cyanide.
Purification Methods
Crystallise it from chlorobenzene, dichloroethane, or dichloromethane [Hall et al. J Org Chem 52 5528 1987]. Storeitat0oina desiccator over NaOH pellets. (It slowly evolves HCN on exposure to moist air CARE.) It can also be sublimed at 120o under vacuum. Also purify it by repeated sublimation at 120-130o/0.5mm. [Frey et al. J Am Chem Soc 107 748 1985, Traylor & Miksztal J Am Chem Soc 109 2778 1987, Fatiadi Synthesis 249 1986, Synthesis 749 1967, Beilstein 2 IV 1245.]
