Elektronenreiche Ruthenium-Thiolat-Komplexe, Synthese und Reaktionen mit Elektrophilen / Electron-Rich Ruthenium Thiolate Complexes, Synthesis and Reactions with Electrophiles

Ruthenium thiolates [cpRu(PR′ (SR)] (PR′ = PPh ,1/2 dppe, 1/2 dppm, R = Me, CH Ph) are obtained from the corresponding chlorides and NaSR. PPh is readily exchanged for CO to give the chiral complexes [cpRu(PPh )(CO)(SR)]. Alkylation with methyl tosylate yields the cations [cpRu(dppe)(SMeR)] and [cpRu(PPh )(CO)(SMeR)] , which were isolated as their PF salts. The neutral carbonyls add dimethyl acetylenedicarboxylate giving five-membered metallocycles.
