A highly efficient system composed of Pd-TPPTS [TPPTS: trisodium salt of tri(m-sulphonylphenyl)phosphine] and halogen-free ionic liquid ([Rmim][p-CH 3 C 6 H 4 SO 3 ], R=methyl, ethyl, n-butyl, n-hexyl, n-octyl, n-dodecyl) has been established for Heck coupling of aryl halides with styrene. Most of the investigated substrates could give the complete conversions (>95%)...
Chiral oxovanadium (IV) Schiff base complex covalently grafted with ionic liquid (IL: 1-(3-aminopropyl)-3-methylimidazolium tetrafluoroborate) has been reported first time. The IL-functionalized complex was found to be an efficient catalyst in the enantioselective oxidation of methyl aryl sulfides to sulfoxides with hydrogen peroxide as an oxidant. Especially, the IL-functionalized complex could be...
