 Abstract    Diastereospeziflsche Alkylierung von [M o(NO)2(S2')2]2 zu chiralen |M o(N O)2(/RS4')l-Komplexen mit chirotopen und prostereogenen Mo-Zentren** Transition Metal Complexes with Sulfur Ligands, LXV* Diastereospecific Alkylation o f [M o(NO)2('S2')2]2" to Chiral [M o(NO)2('RS4')] Complexes with Chirotopic In order to investigate how chirotopicity and stereogenicity o f metal centers influence the enantioselectivity o f metal centered reactions the stereogenic properties o f metal centers in chiral complexes have to be varied without changing their electronic character. Diastereospe­ cific alkylation o f [M o(N O)2('S2')2]2~ by racemic 1,2-dibromopropane and 1,2-dibromobutane yields the title complexes [M o(N O)2('M eS4')] and [M o(N O)2('EtS4')] that differ from the parent compound [M o(N O)2('S4')] with respect to the stereogenicity o f the metal center and allow fu­ ture investigations o f the question raised above.
