 Title    Übergangsmetallkomplexe mit Schwefelliganden  
 Abstract    , LXXIII. Diastereospezifische Dichlormethylierung schwefelreicher IRu'^SRR XPPh^yS/j-Komplexe (SRR' = einzähniger Thioether-oder Thiol-Ligand; 'S4'2-= l,2-Bis(2-mercaptophenylthio)ethan(2-))* Transition Metal Complexes with Sulfur Ligands, LXXIII. Diastereospecific Dichlorom ethylation of Sulfur Rich [Run(SR R')(PPh3)'S4'] Complexes (SR R' = M onodentate Thioether or Thiol Ligand; 'S4': ~ = 1,2-Bis(2-m ercaptophenylthio)ethane(2-)) Under exclusion o f air the thioether and thiol complexes [Ru(SRR')(PPh3)'S4'] ('S4'2-= l,2-bis(2-m ercaptophenylthio)ethane (2 -)) easily react with C H C l, yielding [Ru(Cl)(PPh,)('S4'-C H C L)] in which one thiolato atom o f the 'S4' ligand is diastereospecifical-ly dichloromethylated. In the presence o f air, however, [Rum(Cl)(PPh3)'S4'] is formed. The molecular structures o f [Ru(Cl)(PPh3)('S4'-C H C l:)]-2C H C l3 and [Rum(Cl)(PPh3)'buS4'] have been determined by X-ray crystallography. 'buS4'2-(= 1,2-bis(3,5-di(/-butyl)-2-m ercaptophenylthio)ethane(2-)) is the r-butyl derivative o f the 'S4' ligand. Reasons for ob ­ served diastereospecifity o f alkylation are discussed.
