Generation of Alkoxyl Radicals from N-Alkoxy-2-pyridones

摘要

Alkoxyl radicals have unique characteristic properties such as a facile beta-fragmentation and a hydrogen abstraction due to their high reactivity.Various alkoxyl radical precursors are normally prepared from alcohols and include nitrites,nitrates,hypohalites,sulfenyl ethers,and N-alkoxyphthalimides.Especially,N-alkoxypyridine-2-thiones 3 have attracted a great deal of attention as synthetically useful alkoxyl radical precursors.
