ABSTRACT TITLE.: SOLVENT LESS METHOD FOR PREPARATION OF 1, 2, 3-SELENADIAZOLES The present invention provides a solvent-less method for preparation of 1, 2, 3-Selenadiazole that produces purified 1,2,3-selenadiazole product having a yield in a range of about 40 % to 50 % in a reaction time that is in a range of about 2 to 3 hours. The, 1, 2, 3-selenadiazole product of the present invention is synthesized from cyclic aliphatic ketones, acetophenones, open chain ketones, aromatic ketones and the like which acts as an important precursor for development of metal selenides, quantum dots and magic sized nanocrystals.
