CHARGE-TRANSFER COMPLEXES OF TERTIARY AROMATIC-AMINES WITH TETRACYANOETHYLENE

The tertiary aromatic amines N,N-diethylaniline, N-methyl-N,N-diphenyl amine, and triphenylamine form charge-transfer complexes with tetracya noethylene in solutions, which may subsequently undergo further chemic al reactions. Using UV VIS and EPR spectroscopies it has been found th at for the stability of the complex the delocalization of nonbonding n itrogen electrons, i.e. the electron density in the para position on t he benzene rings of studied amines is important. On the other hand, th e values of the ionization potentials are important mainly for the for mation of charge-transfer complexes.
