Electrochemical dechlorination of some derivatives of 1-chlorophthalazine in dimethylformamide

The electrochemical reduction of some chlorophthalazine derivatives that differ with respect to the nature of the substituent and the heteroring (phthalazines, phthalazones, and 1,2,4-triazolo[3,4-a]phthalazines) on a dropping mercury electrode in dimethylformamide was studied by polarography, coulometry, and preparative electrolysis with isolation and identification of the electrolysis products. It is shown that the carbon-chlorine bond is cleaved initially in the cathode reduction of the investigated compounds to give the corresponding dehalogenated heterocycles.
