The basic aqueous coordination chemistry of Ru-II has been studied using the catalytically important TPPTS phosphine (TPPTS = trisodium salt of 3,3 ',3 ''-phosphinetriylbenzenesulfonic acid) and small gas molecules (H-2, CO, N-2) as ligands. As a result, n ...
1-Fluoro-2-(triethylsilyl)naphthalene and other 1-fluoronaphthalene derivs. bearing a metalation-resistant substituent at the 2-position proved to be totally inert toward base attack. 3-Bromo-1-fluoronaphthalene, readily prepd. from a 2-bromo isomer by dep ...
Interspecies competitive effects on the degradation of two alkyl halides (1-bromo-2-chloroethane, BCA, and 1,1,2-trichloroethane, 1,1,2-TCA) and three vinyl halides (trichloroethylene, TCE; cis-dichloroethylene, cis-DCE; and trans-dichloroethylene, trans-D ...
Reaction of RuCl3 with 1-[2-(1,4-cyclohexadiene-1-yl)alkyl]-3-methylimidazolium chloride (alkyl = Et, butyl) and 1-[2-(1,4-cyclohexadiene-1-yl)ethyl]-2,3-dimethylimidazolium chloride affords a series of dimeric ruthenium complexes of the type [RuCl2(η6-are ...
This work covers homogeneous and biphasic catalysis in ionic liquids and water. The work presented herein is divided into two major parts: catalytic hydrogenation and catalytic hydroformylation. The first part also serves as an introduction to catalysis in ...
A facile pathway to [RuCl2(η6-benzocrownether)]2 complexes is described and crystal structures of the complexes [RuCl2(η6-benzo-15-crown-5)]2 and [RuCl2(η6- ...
Reaction of the dimer [(η5-C5Me5)RhCl(μ2-Cl)]2 with 2 or 4 equiv of the water-soluble phosphine 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (pta) affords [Rh(η5-C5Me< ...
Deprotonation-triggered heavy halogen migrations should become a favorite tool in arene synthesis if their occurrence and outcome could be made predictable. Particularly attractive, though extremely rare, are stop-and-go situations where a first intermedia ...
The labile cobalt (II) complex [Co(TUF)2(Pic)2] with 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (TUF) bidentate and 4-methylpyridine (Pic) monodentate ligands was studied by variable temp. (VT) 19F NMR from 184 to 312 K. In contrast to the solid state, ...
Conversion of unactivated olefins to azides was achieved with high Markovnikov selectivity for a broad range of alkenes by using 6 mol % Co(BF4).6H2O and ligand I, with 3 equiv of tosyl azide as the nitrogen source and simple silanes (e.g., PhSiH3, tetrame ...
