  摘要：

  Reactions of [Rh(PMe3)4]Cl with NaSC6H4-p-Me and with NaSC6H4-p-OMe give Rh(SC6H4-p-X)(PMe3)3 (1, X = Me; 2, X = OMe) whose structures were determined by X-ray crystallography. Complexes 1 and 2 react with HSCrH4-p-Me and HSC6H4-p-OMe, respectively, to give the corresponding cis,mer- and trans,mer-RhH(SC6H4-P-X)2(PMe3)3. Isomerization of the cis,mer product to the trans,mer isomer was observed during the reaction. cis,mer- and trans,mer-RhH(SPh)2(PMe3)3 react with HSC6H4-p-OMe to undergo exchange of the thiolato ligand with the SC6H4-p-OMe group to give mixtures of trans,mer-RhH(SAr)2(PMe3)3 (Ar = Ph or CrH4-p-OMe).

  Thiolatorhodium(I) complexes, Rh(SAr)L-3 (Ar=Ph (1), C6H4-p-Me (2), C6H4-p-OMe (3); L = PMe3), react with HSi(OMe)(3) and with HSiCl3 to give hydrido(silyl)arenethiolatorhodium(III) complexes, RhH(SiX3)(SAr)L-3 (X=OMe, Cl). Crystallographic results of RhH[Si(OMe)(3)](SPh)L-3 as well as NMR spectra of the complexes show octahedral coordination around the Rh center with thiolato and silyl ligands at mutually trans positions and three PMe3 ligands at meridional coordination sites. Hydride(triphenylsilyl)arenethiolatorhodium(III) complexes, RhH(SiPh3)(SAr)L-3 (Ar=Ph, C6H4-p-Me), are obtained from reaction of Rh(SAr)L-3 with excess HSiPh3. The complexes undergo reductive elimination of HSiPh3 in benzene solution at room temperature to regenerate thiolatorhodium(I) complexes and HSiPh3. Thermodynamic parameters of the reaction, Rh(SC6H4-p-Me)L-3 + HSiPh3 = RhH(SiPh3)(SC6H4-p-Me)L-3, are determined as Delta H degrees=-61.7+/-0.7 kJ mol(-1), Delta S degrees=-227+/-15 J mol(-1) deg(-1) and Delta G degrees=5.9 kJ mol(-1) at 298 K. Crystallographic results of RhH(SiPh3)(SAr)L-3 show that the Rh-Si bonds are significantly longer than those of RhH[Si(OMe)(3)](SPh)L-3. Reaction of HSiEt3 with 1-3 does not give oxidative addition products at all. Diarylsilanes, H2SiPh2, H2Si(C6H4-p-Me)(2), H2Si(C6H4-m-Me)(2) and H2Si(C6H4-p-F)(2), react readily with Rh(SAr)L-3 to give the corresponding oxidative addition products, RhH(SiHAr'(2))(SAr)L-3, that do not undergo reductive elimination of diarylsilane in the solutions.
