摘要
In this study, hydroxyl radicals have been converted into methyl radicals by reaction with DMSO which, following capture by the spin-trap alpha-[4-pyridyl N-oxide]-N-t-butyl nitrone (POBN, 1), produced a novel dimethyl product (POBN-Me-2, 3) identified by GC-MS. Identification was confirmed when DMSO was replaced by a deuterated analogue (d(6)-DMSO).
