Under the influence of ultraviolet light, the sodium enolate of diethyl o-biphenylylmalonate (5) in ethanol undergoes intramolecular photoacylation to give ethyl 9-phenanthrol-10-carboxylate (6) in 70% yield. The reaction had been extended to the enolates of phenylethylidenemalonate (7) and phenylethylidenecyanoacetate (8) systems. They cyclized to give the corresponding naphthol derivatives. The reaction represents a new type of photochemical process of organometallic compounds which may have synthetic applications.
