A comparison between the reactivity of [Ru3(CO)12 and [Os3(CO)10(MeCN)2] with 1,2-ethanedithiol (HSCH2CH2SH) and 1,3-propanedithiol (HSCH2CH2CH2SH) is reported. The reaction of [Ru3(CO)12] with 1,2-ethanedithiol at 68°C afforded [Ru2(CO)6(μ-SCH2CH2S)] (1) in 40% yield, whereas the reaction with 1,3-propanedithiol yielded [{(μ-H)Ru3(CO)10}2(μ-SCH2CH2CH2S)] (2) and [Ru2(CO)6(μ-SCH2CH2CH2S)] (3) in 30 and 19% yields respectively. Treatment of [Os3(CO)10(MeCN)2] with 1,2-ethanedithiol gave [(μ-H)Os3(CO)10(μ-SCH2CH2SH)] (4) in 60% yield and with 1,3-propanedithiol it afforded [{(μ-H)Os3(CO)10}2(μ-SCH2CH2CH2S)] (5) in 30% yield. Compounds 1 and 3 both react with equimolar amounts of PPh3 at room temperature to give the monosubstituted products [Ru2(CO)5(μ-SCH2CH2S) (PPh3)] (6) and [Ru2(CO)5(μ-SCH2CH2S) (PPh3)] (7) respectively. When heated to 68°C, compound 2 transformed into 3. The compounds have been characterized by spectroscopic studies, and in the case of 1, 2 and 5 by X-ray crystallography.
