New methods of creation of cyclic bridging and terminal exopolyhedral sulfur-containing substituents in the closo-decaborate anion have been suggested. It has been shown that the reaction of [B10H9SH]2– with 1,2-dibromoethane leads to crosslinking of two cluster anions to give the [B10H9S(CH2)4SB10H9]2– dimer. An analogous reaction with 1,4-dibromobutane yields a derivative with the cyclic tetrahydrothiophene substituent [B10H9S(CH2)4]. Its interaction with tetrahydrothiophene in the presence of a small excess of trifluoroacetic acid leads to the formation of the neutral disubstituted derivative [B10H8(S(CH2)4)2].
