G. Maier et al., HETEROCUMULENES .9. ETHENEDIONE OXIME - PHOTOCHEMICAL GENERATION AND MATRIX-SPECTROSCOPIC IDENTIFICATION, Liebigs Annalen, (3), 1996, pp. 303-306
The title compound 2, a very close derivative of the still elusive eth
enedione (1), was generated by photocleavage of the three different pr
ecursor molecules 7-9 in an argon matrix at 10 K. The structure elucid
ation of monoxime 2 is based on the comparison of the experimental and
calculated IR spectrum.
