Abstract
The transformation of 2-chloroaniline (2-CA ; 95-51-2) was previously studied in aqueous solution (Ishikawa et al. 1989) and in gas phase (Cullin et al. 1990 ; Ishida et al. 1990). The main photoproducts identified in aqueous solution were 2-chloronitrobenzene, 2-chlorophenol and phenol. It was suggested that the former results from the initial photooxidation of the substrate and that the two others resu l t f rom i t s photohydro lys i s . This mechanism cont ras t s wi th the phototransformation of most halogenoaromatic derivatives which lead to an initial C-halogen scission (Boule et al. 1982 and 1985 ; Lipczynska-Kochany 1992). It is also quite different from the transformation of 2-chloroaniline in gas phase observed by means of excimer laser photolysis since the formation of 1,3cyclopentadiene-1-carbonitrile was explained by the intermediate formation of a nitrene.
