The photolysis of the cyclodiene insecticide endosulphan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepin-3-oxide) has been examined under different conditions, including environmental.Two new photometabolites, photo-α-endosulphan and photo-β-endosulphan have been isolated from α- and β-isomers of endosulphan respectively and characterised on the basis of their 13C NMR spectra and other data.Irradiation in polar solvents gives metabolites similar to those formed under biotic conditions.When exposed to sunlight on plant leaves, α-endosulphane not only forms the photometabolite but also undergoes isomerisation to β-isomer.On the other hand β-isomer is relatively more stable.This explains the relatively longer persistence of β-endosulphan in the environment and may have some significance on their toxicity.
