, p. 1364 - 1365 (1988)
The (E)-enol (3), produced by photolysis of o-phthalaldehyde (1) in nitrogen matrix, has been characterized by i.r. spectroscopy.
Radiation Induced Transformations of Benzaldehydes Carrying Formyl-, Nitro- or Nitroso-substituents in the ortho Positions

Transformations induced by X-irradiation of phthalaldehyde (1), o-nitrobenzaldehyde (2), and o-nitrosobenzaldehyde (3) isolated in argon matrices are described.It is shown that the formyl hydrogens in 1, 2 and 3 spontaneously migrate to the respective o-substituents upon ionization.The resulting radical cations are characterized mainly by the ketene and OH stretching bands in their IR spectra. In all cases, X-irradiation led also to the formation of substantial amounts of the neutral tautomers as well as other products in the case of 2 and 3.These are thought to arise by way of the corresponding radical cations which are reneutralized by scavenging some of the electrons ejected from the matrix material upon X-irradiation.
Structure and Photochemistry od Matrix-isolated o-Phthalaldehyde

Two conformers, (EZ) and (EE), were observed in o-phthalaldehyde (1) isolated in nitrogen and argon matrices. the E-enol (5E) generated upon photolysis (λ 313 nm) of the matrix-isolated (1) was stabilized and characterized by UV and IR absorption spectroscopy.Further irradiation of (5E) resulted in intramolecular cyclization (λ > 357 nm) to phthalide (2) or fragmentation (λ = 313 nm) to carbon monoxide and benzaldehyde (7).
