SYNTHESIS AND INTRAMOLECULAR ELECTRON ENTERACTIONS IN TETRACHLORO-4-PYRIDYLCARBONIMIDOYL DICHLORIDE AND ITS DERIVATIVES

Sologub, L. S.,Kisilenko, A. A.,Kukhar', V. P.,Vdovenko, S. I.

, p. 641 - 643 (1983)

Tetrachloro-4-pyridylcarbonimidoyl dichloride was synthesized, and products of the reaction of the latter with amines, triethyl phosphite, and dimethylformamide (DMF) were obtained; acid hydrolysis was also carried out.The character of the intramolecular interactions between the ? system of the pyridine ring and the C=N bond was investigated by IR spectroscopy.
