Description

Technical field [0001] The present invention belongs to the synthesis of pharmaceuticals, chemical industry, mainly involving N- bis-benzenesulfonyl-1-trifluoroethane phenylselenyl derivatives and their synthesis and applications. Background technique [0002] Trifluoromethyl and selenium based compound has good biological activity, in addition, the organic selenium compounds having important physical and pharmacological activity are widely used in material science and drug design. Constructing a compound having both selenium and trifluoromethyl structure may be provided having more or develop special nature of the class structure. Since the product contains more of such reactive functional groups, the synthesis is difficult, therefore, the product of the synthesis of such structure is not found. Inventive content [0003] The present invention fill the gaps in the synthesis method of such compounds, synthetic methods proposed trifluoromethyl-step synthesis of compounds having b...
