An Unusual Behavior of π-Vinyl Alcohol Complexes of Transition Metals
Although the usefulness of polyvinyl alcohol [PVA] polymer has long been recognized, no work has been reported on the vinyl alcohol moiety itself. This is due to the fact that the existence of free vinyl alcohol has not yet been shown. It has been postulated that a small percentage of this unstable specie, vinyl alcohol, exists in situ in an equilibrium with acetaldehyde.1 However, it has been claimed that vinyl alcohol forms stable organometallic complexes with transition metal ions. These vinyl alcohol complexes of transition metals have been proposed as being π-bonded to the metal.
