Simple and readily available alkyl sulfoxides are shown to be suitable precursors to radicals. Alkyl sulfoxides, N-methoxy pyridinium salts and fluoride anions form electron donor–acceptor (EDA) complexes, which, upon visible-light irradiation, undergo a radical chain process to give various pyridine derivatives.
简单且容易获得的烷基亚砜被证明是自由基的合适前体。烷基亚砜、N-甲氧基吡啶鎓盐和氟化物阴离子形成电子供体-受体 (EDA) 配合物,在可见光照射下,它们经历自由基链过程,得到各种吡啶衍生物。
