  Tungsten(0) η²-Thiophene Complexes:  Dearomatization of Thiophene and Its Facile Oxidation, Protonation, and Hydrogenation

  摘要：

  Complexes of the form TpW(NO)(PMe3)(n(2)-thiophene) have been synthesized in 31-40% yield by reduction of TpW(NO)(PMe3)(Br) in the presence of the thiophene ligand. The dynamics of protonation and the subsequent deprotonation for the corresponding 2H-thiophenium complexes have been investigated. Hydrogenation of the uncoordinated double bond was accomplished, and sulfur-carbon, sulfur-oxygen, and carbon-carbon bond-forming reactions were explored with these complexes.
