A study on UV-degradation dynamics of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) and its analogues 2,3,7,8-tetrachlorophenoxthin (2,3,7,8-TCPT) and 2,3,7,8-tetrachlorothianthrene (2,3,7,8-TCTR) in solvents CHCl3 and CCl4 was completed. The results indicated that they were degradated by UV in different way in different solvent. The degradation of 2,3,7,8-TCDD and 2,3,7,8-TCPT are pseudo-first-order reactions in CHCl3, but complex reactions in CCl4; the degradation of 2,3,7,8-TCTR is a zero-order reaction in CHCl3, but a pseudo-first-order reaction in CCl4. All of the three compounds disappeared in CCl4 much faster than in CHCl3 under 254 nm UV-irradiation.

Reactions of sulfuryl chloride with dibenzothiophene and related heterocyclic systems have been studied. It is shown that under different conditions, C- or S-halogenation of the heterocycle takes place. A series of new chlorine derivatives of dibenzothiophene, phenoxathiin and thianthrene have been synthesized and characterized. 1997 Plenum Publishing Corporation.
