Thermal experiments between 300°C and 500°C were performed with fly ash of a municipal waste incineration plant which had been spiked with elemental sulfur. The influence of elemental sulfur on the heterogeneous carbon-decomposition and the de-novo-synthesis of polychlorinated compounds was investigated. Compounds such as polychlorinated dibenzodioxins, dibenzofurans, benzenes, benzoand dibenzothiophenes, Cl4-thiophene, Cl4- thienothiophene, Cl7- and Cl8-phenylthiophene were quantified. Apart from those, other intermediate structures were determined. These compounds are mainly aromatics with a vinyl- or butadienyl-group, stabilized by perchlorination. In detail, the compounds are Cl7- and Cl8-styrene, Cl10-vinylnaphthalenes, Cl10-phenylbutadiene, Cl10-octatetraene, Cl10-bis-butadienylsulfides and Cl12-stilbenes.

A new synthesis of perchlorotolane (perchlorodiphenylacetylene; I) is described.It dimerizes at high temperature to give perchloro-1,2,3-triphenyl-naphthalene (III) and perchloro-2,3,8-triphenylbenzofulvene (IV).Under the same conditions the latter yields
