| Abstract: | Abstract 3,6-Dialkyl-2,5-Dithioxo-1,4,2λ5,5λ5-dithiadiphosphorinan-2,5-disulfides (1) react with PSCI3, to give 3,6-Dialkyl(diaryl)-1,4-dithioxo-2,5,7-trithia-lλ5,4λ5 diphosphabicyclo2.2.1]heptanes (2). The reaction mechanism of their formation. and the stereochemistry are discussed. By reduction of 2 with (n-C4H9)3P or (C6H5),P 3,6-Dialkyl-2,5,7-trithia-1λ3,4λ3-diphosphabicyclo2.2.1]heptanes (3) are formed. 2c reacts with one mole of (C6H5)3P to give 3,6-Diethyl-l-thioxo-2,5,7-trithia-lλ5,4λ3- diphosphabicyclo(2.2.1]heptane, 4c. 3,6-Dialkyl-2,5-dithioxo-1.4,2λ5,5λ5-dithiadiphosphorinan-2,5-disulfide (I) reagieren mit PSCI3 zu 3,6-Dialkyl(diaryl)-1,4-dithioxo-2,5,7-trithia-lλ5,4λ5-diphosphabicyclo2.2.l]heptanen (2). Der Reaktionsmechanismus ihrer Bildung und ihre Stereochemie werden diskutiert. Die Reduktion von 2 mit (n-C4H9)3,P oder (C6H5)3P führt zu 3,6-Dialkyl-2,5,7-trithia-1λ3,4λ3-diphosphabicyclo2.2.1] heptanen(3). 2c reagiert mit einer äquimolaren Menge (C6H5)3,P zu 3,6-Diethyl-l-thioxo-2,5,7-trithia-lλ5,4λ3- diphosphabicyclo2.2.1]heptan, 4c. |
