“…Analysis of the crude solids by 1 3 c NMR or by reverse phase HPLC showed that only one product had been formed in each experiment. These results follow the general trend (15,16) that palladium(I1) compounds react with thioethers to produce, predominantly, one compound with square planar geometry (X-ray analysis described later confirmed that both l b and l c have a trans square planar configuration).…”

[Traduit par la redaction] Introduction We previously (1) reported the preparation and structural determination of trans-dichloro bis(2,3-dihydrobenzo[b]thiophene)palladium(II) l a , which was of interest regarding mechanisms for the catalytic hydrodesulfurization of benzo-[blthiophene (BT) and the reaction of BT with water at elevated temperatures in the presence of aqueous latinum trans-Dichlorobis

“…In this context, some years ago we reported highly efficient and chemoselective hydroformylation [10][11][12] and hydrogenation [8] reactions using water-soluble complexes derived from the interaction between Rh(CO) 2 (acac) or [Ir(COD)Cl] 2 , respectively, with human serum albumin (HSA). Previous studies, carried out by us on the catalytic system Rh/HSA, showed an outstanding correspondence between the surface distribution of Rh and S atoms of the protein, therefore we hypothesized that the metal atom mainly interacts with the sulphur atoms [13,14]: the great affinity of "soft" metals, such as rhodium, for the thiolic group is well known [15]. As a matter of fact many rhodium complexes modified with thioligands have been successfully employed in catalytic reactions in homogeneous phase in organic solvents [16][17][18][19][20][21][22][23].…”

a b s t r a c tRh(DHTANa) is a new water-soluble catalyst easily obtained by mixing in water the catalytic precursor [Rh(COD)Cl] 2 and the dihydrothioctic acid sodium salt (DHTANa). This catalyst showed to be very active in the hydrogenation of unsaturated substrates as 2-cyclohexen-1-one, the biomass-derived furfural and acetophenone. In this last case the catalytic system obtained by using as water-soluble ligand (R)-(DHTANa) afforded (R)-1-phenylethanol with very modest enantioselectivity. Rh(DHTANa) was active also in the aqueous biphase hydroformylation of styrene producing exclusively the two corresponding aldehydes with 80-86% selectivity toward the branched aldehyde 2-phenylpropanal. This new catalytic system was easily recycled in both hydrogenation and hydroformylation processes and no leaching phenomenon was observed.

“…Once formed, 2 should form complexes with platinum metal species that could be intermediates in the formation of 3. Although many thioether complexes have been prepared (19) volving the 2,3-dihydrobenzothienyl ligand has been reported. To establish that complexes with this relatively bulky ligand can exist, 2 was reacted with PdC12.…”

. Can. J. Chem. 69,590 (1991). The desulfurization of benzo [b]thiophene 1 with aqueous transition metal species in the presence of various hydrocarbons at elevated temperatures is described. Mechanistic studies have shown that treatment of 1 with solutions of RuC13 and other platinum metal species results in the formation of 2,3-dihydrobenzo[b]thiophene 2 and ethylbenzene 3 as major products. Metal coordinated species are probable intermediates in the formation of 2 and hydrocarbon products. 2 readily coordinates to PdCI2 to form square-planar trans-dichlorobis(2,3-dihydrobenzo[b]thiophee) palladium(II), which decomposes to ethylbenzene at 300°C. The crystal structure of the complex was determined by a single crystal X-ray diffraction study. The complex crystallized in the monocliriic space group C 2 / c with Z = 8 in a cell of dimensions a = 23.057 (3), b = 9.71 1 (1), c = 15.227 (2) A and p = 99.74(1)". The structure was solved by the Fourier method and was refined by full-matrix least-squares calculations to R = 0.042 for 2537 observed data with I > 2.5u(I).
