| Abstract: | New Cyclic and Bicyclic Systems Made of Phosphorus, Carbon, and Sulfur By reaction of P4S10 with tertiary alkyl amines dialkylammonium salts of 3, 6- dialkyl1-2, 5-dithioxo-2λ5, 5°5-1.4.2.5]dithiadiphosphorinan-2, 5-dithiols (V) are obtained. By pyrolysis the 3,6-dialkyl-2, 5, 7-trithia-1, 4-diphosphabicyclo2.2.1] heptane-1,4-disulfides are formed ( VIII ). The result of an X-ray structural analysis of 3,6-di-isopropyl1-2,5,7-trithia-1,4-diphosphabicyclo 2.2.1]heptane-1,4-disulfide ( VIIIc ) is reported. |
