Abstract:
Chiral thiolate complexes [Cp(NO)(Ph 3 P)ReSCH 2 R] (R=Ph, 4-C 6 H 4 Cl, 4-C 6 H 4 OMe, H, Me) are obtained from [Cp(NO)(Ph 3 P)ReCH 3 ] by acid cleavage in the presence of thiol and subsequent deprotonation. Small amounts of (chloromethyl)thioether complexes [Cp(NO)(Ph 3 P)ReS(CH 2 Cl)CH 2 R]BF 4 are formed when dichloromethane is used as a sol vent in this reaction. Hydride abstraction using [Ph 3 C]PF 6 converts the thiolate complexes into ionic thioaldehyde complexes [Cp(NO)(Ph 3 P)Re(η 2 -S=CHR)]PF 6 . These are obtained as pure (RR,SS)-diastereomers as shown spectroscopically and by X-ray structure determination of [Cp(NO)(Ph 3 P)Re(η 2 -S=CHPh)]PF 6 . Crystals are monoclinic, space group I2/a (No. 15), a = 25.877(3), b = 18.785(2), c = 13.768(1) Å , β = 104.93(1)°, Z -8.
