Treatment of the ruthenium chloride, CpRu(PPh3)2Cl, with the alkynyldithiocarboxylate anions, RCCCS2-, in refluxing THF affords the chelate complexes CpRu(PPh3)(κ2S,S-S2CCCR) (1) (R = But (a), Bun (b), Ph (c), SiMe3 (d)) in high yield. The room temperature reaction of the solvated species, [CpRu(PPh3)2(NCPh)]+, with the alkynyldithiocarboxylate anions, RCCCS2-, produces the chelate complexes 1 and the mono-coordinated complexes CpRu(PPh3)2(κS-S2CCCR) (2). Complexes 2 are converted to 1 in solution so that they were characterized spectroscopically.
Graphical abstractTreatment of the ruthenium chloride, CpRu(PPh3)2Cl, with RCCCS2-, in refluxing THF affords CpRu(PPh3)(κ2S,S-S2CCCR) (1). The X-ray structure of CpRu(PPh3)(κ2S,S-S2CCCBut) (1a) was determined. The room temperature reaction of [CpRu(PPh3)2(NCPh)]+, with RCCCS2-, produces the chelate complexes 1 and the mono-coordinated complexes CpRu(PPh3)2(κS − S2CCCR) (2). Complexes 2 are converted to 1 in solution so that they were characterized spectroscopically.Figure optionsDownload full-size imageDownload as PowerPoint slide
