<br/><br/> This work has been carried out to investigate the synthesis of new derivatives of 3- cyanopyridine - 2 (1H ) - thione cotaining cycloketones . The reactions of the latter compounds with halogenated compounds were studied . The studied halogenated compounds were Ü - chloroacetanilides, 3 - bromoacetylcoumarin , 3- chloropentan - 2, 4 - dione and - bromoacetoacetanilide
