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

Abstract

Ruthenium thiolates [cpRu(PR′3)2(SR)] (PR′3 = PPh3,1/2 dppe, 1/2 dppm, R = Me, CH2Ph) are obtained from the corresponding chlorides and NaSR. PPh3 is readily exchanged for CO to give the chiral complexes [cpRu(PPh3)(CO)(SR)]. Alkylation with methyl tosylate yields the cations [cpRu(dppe)(SMeR)]+ and [cpRu(PPh3)(CO)(SMeR)]+, which were isolated as their PF6 - salts. The neutral carbonyls add dimethyl acetylenedicarboxylate giving five-membered metallocycles.
