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).
