REACTION OF DIAZONIUM SALTS WITH THE TETRACYANOQUINODIMETHANE ANION-RADICAL

Diazonium salts react with the tetracyanoquinodimethane anion-radical with the release of nitrogen and the formation of 1,2-bis-1,1,2,2-tetracyanoethane, where R = H, Me OMe, Cl, CN, NO2, NMe2.During the pyrolysis of these compounds and subsequent irradiation of the reaction mass with UV light 7-(4-R-phenyl)-7,8,8-tricyanoquinodimethanes (R = H, Me, Cl, OMe, NMe2) were obtained with small yields.
