In the crystal structure of the title compound, C 15 H 14 Cl 2 S 2 , two substituted thiophene rings are cis positioned with respect to the double bond of a cyclopentene ring. The ring skeleton of the molecule is not planar.
von 2 h die Losung von 6,52 g (56,3 mmol) Acetessig&ummethylester in 30 ml Xylen zu und destillierte dabei uber eine Kolonne Methanol und Xylen ab. Nach weiteren 60 min Erhitzen auf 150°C destillierte nur noch Xylen ab. Die auf 30 ml eingeengte Liisung wurde mit 150ml Petrolether (Sdp. 35-50°C) vers
The enone fragment, the thiophene ring and the benzene ring of the title molecule, C 13 H 9 ClOS, are all essentially individually planar. The thiophene ring is disordered over two sites, corresponding to a rotation of approximately 180 about the single C-C bond to which it is attached. The crystal
The cyclopentene ring of the title compound, C 15 H 14 Cl 2 S 2 , is almost planar. The two thiophene rings are twisted out of the mean plane of the cyclopentene ring by 39.97 (5) and 50.84 (5) .
