Anodic fluorination of 2-cyano-1-methylpyrrole using Et3N·2HF in an undivided cell provided the corresponding 5-fluoropyrrole and 2,5,5-trifluoro-1-methyl-3-pyrrolin-2-carbonitrile while the use of Et3N·3HF afforded selectively the latter product, which was readily hydrolyzed to isolable 5,5-difluoro-1-methyl-3-pyrroline-2-one. This is the first report of successful anodic fluorination of a pyrrole
在未分格的电池中使用Et 3 N·2HF对2-氰基-1-甲基吡咯进行阳极氟化反应,提供了相应的5-氟吡咯和2,5,5-三氟-1-甲基-3-吡咯啉-2-腈。 Et 3 N·3HF选择性地提供了后者的产物,其易于水解为可分离的5,5-二氟-1-甲基-3-吡咯啉-2-酮。这是吡咯衍生物成功进行阳极氟化的第一份报告。
