ChemInform Abstract: 3- and 3,6-Silylated 2-Pyridinethiols: New Bulky Bidentate Ligands and Their Silver and Copper Clusters.
Abstract
The mono- and disilylated pyridinethiols (I) and (V) are prepared by the one-pot reaction of pyridinethiol (III) with LDA and addition of the corresponding chlorosilanes (II) or (IV) depending on the silane substituents.
ChemInform Abstract
The mono- and disilylated pyridinethiols (I) and (V) are prepared by the one-pot reaction of pyridinethiol (III) with LDA and addition of the corresponding chlorosilanes (II) or (IV) depending on the silane substituents. (Ia) reacts with AgNO3 (VI) or the Cu(I) complex (VII) to give the hexanuclear, paddlewheel complexes (VIII). The structures of these isomorphous complexes (VIIIa) (space group C2/m, Z=2) and (VIIIb) (A2/m, Z=2) are determined by X-ray analysis. MS2N coordination is thus achieved for the first time. The large SiMe3 group of the ligand prevents polymerization which is observed for complexes of the parent compound.
