New Enantiopure Bis(thioether) and Bis(sulfoxide) Ligands from Benzothiophene

The C2‐symmetric compound 2,3,2,3‐tetrahydro‐2,2‐bi(benzo[b]thiophenyl) and three diastereomeric bis(oxide) derivatives can be synthesized in a few steps from benzo[b]‐thiophene by oxidative homocoupling of (R)‐2,3‐dihydro‐benzo[b]thiophene 1‐oxide. This new family of enantiopure bis(thioether) and...

More Information
Summary:The C2‐symmetric compound 2,3,2,3‐tetrahydro‐2,2‐bi(benzo[b]thiophenyl) and three diastereomeric bis(oxide) derivatives can be synthesized in a few steps from benzo[b]‐thiophene by oxidative homocoupling of (R)‐2,3‐dihydro‐benzo[b]thiophene 1‐oxide. This new family of enantiopure bis(thioether) and bis(sulfoxide) ligands forms stable chelating PdII complexes. The fused pentacyclic structure of the complexes imparts a rigid chiral environment around the metal centre. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
