Аннотация:Electrophilic sulfenylation, selenenation, and halogenation of bicyclo[2.2.1]heptenes containing CF3 or NO2 group in position endo-5 were studied. The sulfenylation and selenenation were accomplished by arylsulfene- and arylselenenamides activated by POHal(3) (Hal = Br, Cl), and iodination was performed by KICl2. The reactions are regiospecific and involve an exo-attack of the electrophilic fragment (arylthio or arylseleno group or iodine) on the C=C bond atom located closer to the CF3 or NO2 group.
