title: Mild mono and double demethylation in dimethylsulfonium substituted ruthenacarborane complexes. A regioselective reaction.
abstract: Reaction of [RuCl(2)(eta(6)-C(6)H(6))](2) with [10-(CH(3))(2)S-7,8-nido-C(2)B(9)H(10)](-) or [9-(CH(3))(2)S-7,8-nido-C(2)B(9)H(10)](-) afforded the expected cationic complexes [Ru(eta(5)-n-(CH(3))(2)S-7,8-C(2)B(9)H(10))(eta(6)-C(6)H(6))](+)(n= 10, (1); 9, (3)), but also the unexpected neutral Ru(eta(5)-10-HS-7,8-C(2)B(9)H(10))(eta(6)-C(6)H(6))(2) or Ru(eta(5)-9-(CH(3))S-7,8-C(2)B(9)H(10))(eta(6)-C(6)H(6))(4) by double and mono demethylation of the (CH(3))(2)S moiety, respectively.
