Fluxional pentacarbonyltungsten(0) complexes of the thioaldehyde and thioketone valence isomers of 1,6,6aλ4-trithiapentalenes
Abstract
The reaction of silver nitrate with tetraethylammonium pentacarbonyliodotungstate(0) in the presence of 1,6,6aλ4- trithiapentalenes gives pentacarbonyltungsten(0) complexes of the thioaldehyde and thioketone valence isomers of 1,6,6aλ4-trithiapentalenes; the symmetrically substituted complexes are fluxional.
