Synthesis of 1,4-bis(dicyanomethylene) cyclohexane and use thereof in the synthesis of 7,7,8,8-tetracyanoquinodimethane

摘要

1,4-bis(dicyanomethylene) cyclohexane is the chemical of choice for the synthesis of TCNQ. The present invention provides a simple, convenient, three-step synthesis of 1,4-bis(dicyanomethylene) cyclohexane from hydroquinone which uses water as the reaction solvent.
