to proceed via electrophilic attack by the 2,4-dinitrobenzene-sulphenium ion, or its precursor. Transfer of oxygen from the ortho-nitro-group to the sulphur atom for 2,4-dinitrobenzenesulphenyl derivatives is demonstrated under photolytic conditions. Evidence is accumulated for the formation of a nitrene type of intermediate in certain of these redox reactions.
芳香族硫化物是通过将2,4-二硝基苯磺基乙酸苯酯与芳香族化合物光解制备的。该反应是一般性的,并且显示是通过2,4-二硝基苯-s离子或其前体的亲电攻击而进行的。在光解条件下,证明了氧从2,4-二硝基苯磺基苯基衍生物的邻硝基转移至硫原子。在某些氧化还原反应中,积累了形成亚硝基类型中间体的证据。
