| Abstract: | Treatment of the ruthenium chloride, CpRu(PPh3)2Cl, with the alkynyldithiocarboxylate anions,  , in refluxing THF affords the chelate complexes CpRu(PPh3)(κ2S,S-S2CC CR) (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,  , 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. |
