A variety of hitherto unknown symmetrical and unsymmetrical pyrimidyl chalcogen compounds have been synthesized and characterized by elemental analysis using various spectroscopic techniques viz. NMR 1H, 13C, 77Se and infrared. Two different methodologies were employed. The first method involves the use of hydrazine hydrate as reducing agent to generate dichalcogenide anions followed by reaction with 2, 4-dichloropyrimidine to give the dichalcogenide compounds in good yield. The second method employs chlorine-magnesium exchange of 2,4-dichloropyrimidine using iso propyl magnesium chloride. The synthesis of the mixed phenyl pyrimidyl selenides have been achieved using sodium borohydride in ethanol as a reductive reagent to cleave Se-Se bond followed by alkylation with 2-chloro-4, 6-dimethylpyrimidine and 2, 4-dichloropyrimidine.
Preparation and characterization of symmetrical bis[4-chloro-2-pyrimidyl] dichalcogenide (S, Se, Te) and unsymmetrical 4-chloro-2-(arylchalcogenyl) pyrimidine: X-ray crystal structure of 4-chloro-2-(phenylselanyl) pyrimidine and 2-(p-tolylselanyl)-4-chlor

Synthesis of a novel class of multinucleate pyrimidine chalcogen (S/Se/Te) derivatives has been successfully attempted for the first time by the selective substitution of chlorine at the C-2 position of 2,4-dichloropyrimidine with nucleophilic dichalcogen
