  New Insights into the Photoreactivity of the Organophosphorus Pesticide Fenthion:  A σ Aryl Cation as a Key Intermediate in the Photodecomposition

  摘要：

  The primary photodegradation processes of fenthion (FN), one of the most photosensitive pesticides used in agriculture, have been investigated by combining laser flash photolysis and steady-state measurements. The triplet state of FN is produced quite efficiently (Phi(isc) similar to 0.3). However, this excited state does not seem to trigger the primary photodecomposition pathways of the pesticide. It is demonstrated that FN undergoes photoheterolysis via the excited singlet state and gives the corresponding singlet "sigma aryl cation". Chemical evidence for the generation of this transient species is given by trapping with typical "sigma nucleophiles" such as chloride and methanol. This photodegradation mechanism is, in part, quite different with respect to what is known to date and may account for the formation of the O,O-dimethyl S-[3-methyl-4-(methylthio)phenyl] phosphorothioate discovered as a novel photodegradation product of FN.

  A shaped chitin body containing a high content of a physiologically active substance, such as a drug to be used for the cure or prevention of disease, is prepared by incorporating said physiologically active substance into a dope comprising (a) a water-insoluble chitin, (b) lithium chloride, and (c) N-methylpyrrolidone and/or dimethylacetamide, with the amount of said physiologically active substance incorporated being 0.5 wt. % or more with respect to the amount of the chitin contained in said dope, and there after coagulating the resulting mixture with a coagulant to obtain a shaped body. The high content of the physiologically active substance thus incorporated in the shaped chitin can be slowly released therefrom over a long period of time. The shaped-chitin of the present invention is characterized by long duration of the physiological activity of the active substance contained therein.
