Description

Solid; [Merck Index] Colorless crystalline solid; [Alfa Aesar MSDS]

Sources/Uses

Used to make spiro compounds, in modified Diels-Alder reactions, and as an aromatizing agent; [Merck Index] "Because of its planarity and its ability to accept electrons, TCNE has been used to prepare numerous organic superconductors, usually by serving as a single electron oxidant of an organic electron donor. Such charge-transfer salts are sometimes called Bechgaard salt. TCNE hydrolyzes in moist air to give hydrogen cyanide and should be handled accordingly." [Wikipedia]

Comments

Causes conjunctive irritation and respiratory obstruction in ocular lethal-dose studies of rabbits; Causes convulsions, regional or general arteriolar or venous dilation, dyspnea, and respiratory obstruction in oral lethal-dose studies of mice; [RTECS] A skin and strong eye irritant; Highly toxic by ingestion and skin absorption; [Alfa Aesar MSDS] See "NITRILES." See "Hydrogen cyanide."
