Metallorganische Lewis-Säuren, XLI [1] / Organometallic Lewis Acids, XLI [1]

Addition of [Re(CO)5]+ (as (OC)5ReFBF3) to compounds of the type Cp(OC)2Fe—C(S)SR (R = CH3, Fe(CO)2Cp) gives the products [Cp(OC)2Fe—C(SCH3)S—Re(CO)5]+BF4- (1) and {Cp(OC)2Fe—C[SFe(CO)2Cp]—S—Re(CO)5}+BF4- (2), respectively. Complex 2 has been characterized by an x-ray structure analysis. From (OC)5ReFBF3 and (Ph4P)2(OC)2Fe(η2—CS2), the complex [(Ph3P)2(OC)2Fe[μ2-η2(C,S):η1 (S′)]Re(CO)5]+BF4- (3) has been obtained.
