The photoirradiation of 3,5-disubstituted 2-isoxazolines and Fe(CO)5 in MeOH causes the N–O and C4–C5 bond cleavage 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.
3,5-二取代的 2-异恶唑啉和 Fe(CO)5 在 MeOH 中的光照射导致 N-O 和 C4-C5 键断裂产生两个醛和酮片段,而 2-异恶唑啉在 5 -位置产生额外的β-羟基-和β-甲氧基酮。
