| Chiral Thioaldehyde Complexes of Rhenium, X-Ray Structure Determination of [Cp(NO )(Ph3P)R e(i/2-S=CHPh)]PF6 [1]  | | | Abstract
| Chiral thiolate com plexes [C p(N O)(Ph3P)R eSC H 2R] (R = Ph, 4-C6H 4Cl, 4-C6H4OM e, H, Me) are obtained from [C p(N O)(Ph3P)R eC H 3] by acid cleavage in the presence of thiol and subsequent deprotonation. Small amounts of (chloromethyl)thioether com plexes [C p(N O)(Ph3P)R eS(C H 2C l)C H 2R ]BF4 are formed when dichloromethane is used as a sol vent in this reaction. Hydride abstraction using [Ph3C]PF6 converts the thiolate com plexes into ionic thioaldehyde com plexes [C p(N O)(Ph3P)Re(?72-S=CHR)]PF6. These are obtained as pure (RR.SS)-diastereom ers as shown spectroscopically and by X-ray structure determ i nation of [C p(N O)(Ph3P)Re(?/2-S=CHPh)]PF6. Crystals are monoclinic, space group 12/a (No. 15), a = 25.877(3), b = 18.785(2), c = 13.768(1) A , ß = 104.93(1)°, Z -8. | | |
