Syntheses of Polythianferrocenophanes and Polythian.nferrocenophanes. Marocyclic Polysulfide Ligands Containing a Ferrocene Nucleus

Abstract 1,1′-Bis(2-chloroethylthio)ferrocene reacted with disodium 1,2-ethanedithiolate to give 1,4,7,10-tetrathia10ferrocenophane and 1,4,7,10,22,25,28,31-octathia10.10ferrocenophane, along with unexpected 1,4,7-trithia7ferrocenophane, 1,4,7,10,13-pentathia13ferrocenophane and 1,4,7,10,13,25,28,31,34-nonathia10.13ferrocenophane. The reaction of 1,1′-bis(2-chloroethylthio)ferrocene with disodium 1,3-propanedithiolate gave 1,4,-8,11-tetrathia11ferrocneophane. 1,1′-Bis(3-chloropropylthio)ferrocene reacted with disodium 1,2-ethanedithiolate and 1,3-propanedithiolate to afford 1,5,8,12-tetrathia12ferrocenophane and 1,5,8,12,24,27,31,34-octathia12.12ferrocenophane, and 1,5,9,13-tetrathia13ferrocenophane, respectively. The structural features of the above polythianferrocenophanes are also discussed on the bases of their spectral data.
