  摘要：

  eta(2)-Phosphinocarbene complexes of tungsten containing a trimethyl-phosphine ligand show an amphiphilic behavior. With the Lewis acid SMe(+) an electrophilic attack occurs at the metal-carbon double bond to give 1-tungsta-2-phospha-4-thia-bicyclo[1.1.0]butane complexes. On the contrary the Lewis base, PMe(3), adds at the carbene carbon atom to yield a cationic trimethylphosphoraneylidene complex. However, treatment of dicarbonyl(eta(5)-cyclopentadienyl)[eta(2)-(diphenylphosphino)methylcarbene]-tungsten-tetraphenylborate with the less nucleophilic triethylamine causes deprotonation at the methyl group providing dicarbonyl(eta(5)-cyclopentadienyl)-eta(2)-diphenylphosphinovinyltungsten.
