RING CLEVEAGE REACTIONS OF SUBSTITUTED 2-ISOXAZOLINES BY PENTACARBONYLIRON UNDER ULTRAVIOLET IRRADIATION

Article abstract of DOI:10.1246/cl.1983.51

The photoirradiation of 3,5-disubstituted 2-isoxazolines and Fe(CO)5 in MeOH causes the N-O and C4-C5 bond cleveage to give two fragments of aldehydes and ketones, while that of 2-isoxazolines having no substituent at 5-position gives additional β-hydroxy- and β-methoxyketones.
