Abstract

The treatment of mercaptothioethers CH3(SCH2)nSH, n = 1,2,1,2 with equivalent amounts of iodine and triethyl amine leads to the formation of 2.4.5.7-tetrathiaoctane 3 and 2.4.6.7.9.11-hexathiadodecane 4. Oxidation of ethanedithiol-1.2 5 leads to polyethylene disulfide 6, 1.2.5.6-tetrathiacyclooctane 7 and 1.2.5.6.9.10.13.14-octathiacyclohexadecane 8, whereas bis-(mercaptomethyl)-sulfide 9 is converted to polymeric sulfides or disulfides and 1.2.4.6-tetrathiacycloheptane 10.

Die Behandlung von Mercaptothioethern CH3(SCH2)nSH, n = 1,2,1,2 mit äquivalenten Mengen von Jod und Triethylamin führt zur Bildung von 2.4.5.7-Tetrathiaoktan 3 und 2.4.6.7.9.11-Hexathiadodekan 4. Die Oxidation von Ethandithiol-1.2 5 führt zu Polyethylendisulfid 6, 1.2.5.6-Tetrathiacyclooktan 7 und 1.2.5.6.9.10.13.14-Oktathiacyclohexadekan 8, wogegen Bis-(mercaptomethyl)-sulfid 9 in polymere Sulfide oder Disulfide und 1.2.4.6-Tetrathiacycloheptan 10 umgewandelt wird.
