Abstract

Reaction of [RuCl2(eta(6)-C6H6)](2) with [10-(CH3)(2)S-7,8-nido-C2B9H10](-) or [9-(CH3)(2)S-7,8-nido-C2B9H10](-) afforded the expected cationic complexes [Ru(eta(5)-n-(CH3)(2)S-7,8-C2B9H10)(eta(6)-C6H6)](+) (n=10, (1); 9, (3)), but also the unexpected neutral Ru(eta(5)-10-HS-7,8-C2B9H10)(eta(6)-C6H6) (2) or Ru(eta(5)-9-(CH3)S-7,8-C2B9H10)(eta(6)-C6H6) (4) by double and mono demethylation of the (CH3)(2)S moiety, respectively.
