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
C2-对称化合物2,3,2,3-四氢-2,2-双(苯并[b]噻吩)和三种非对映双(氧化物)衍生物可以从苯并[b]-噻吩通过几个步骤合成(R)-2,3-二氢-苯并[b]噻吩1-氧化物的氧化均偶联。这个新的对映体纯双(硫醚)和双(亚砜)配体家族形成稳定的螯合 PdII 复合物。配合物的稠合五环结构在金属中心周围赋予刚性手性环境。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
