Reaction of the tricarbollide anion [7,8,9-C3B8H11](-) (1a) with the naphthalene complex [CpRu(C10H8)](+) under visible light irradiation in CH2Cl2 gives the 12-vertex closo-rthenacarborane 1-Cp-1,2,3,5-RuC3B8H11 (2; 87% yield). This complex was also obtained by reaction of 1a with CpRu(cod) Cl (97%). Upon heating at 80 C in toluene 2 rearranges into isomer 1-Cp-1,2,4,10-RuC3B8H11 (3; 63%). Irradiation of 1a with [CpRu(C10H8)](+) in acetone gives the 11-vertex closo-1-Cp-1,2,3,4-RuC3B7H10 (4; 32%). The latter was also prepared by reaction of 1a with [CpRu(MeCN)(3)]+ (59%). Compound 2 slowly undergoes cage contraction in acetone giving 4.
