• 論文の詳細を見る

• The reaction mechanism of the photochemical reaction of alkanenitronate anions to form hydroxamic acids was explored on the basis of the potential energy curves obtained by means of MINDO/3 CI calculations. The <I>O</I>-oxaziridine was calculated to be not an intermediate, but an unstable transient species in this photoreaction. This is different from the photoisomerization of methyleneamine <I>N</I>-oxide derivatives into the corresponding amides, in which the oxaziridine is considered to be an intermediate. The proposed reaction mechanism elucidates well the regioselectivity observed in the photochemical formation of hydroxamic acids from nitronate anions.
