Synthesis and Characterization of Series of Promising Decontaminants for Organophosphorus Compounds

A novel 6,7-epoxy, N N', N'-trichloro-t-cinnamaldehyde semicarbazone has been synthesized, by conversion of t-cinnamaldehyde into its very stable semicarbazone derivative, followed by both epoxidation and N-chlorination (electrophilic) respectively. Calcium hypochlorite was the source of electrophilic chlorine. The physical characterization is reported and achieved for each member of the series by mass, FT-IR and ¹H NMR studies. Both the epoxide as well as the trichoro-derivatives are expected to act as suitable and efficient decontaminants for the toxic organophosphorus (C-O-P and C-N-P) compounds due to their functions as the oxidizing agents mainly.
