The reaction of 2-methylthio- or 2-phenylthioarylimines with di-iso-propyl peroxydicarbonate (DPDC) is described. The phenylthio-derivatives undergo cyclization to benzothiazoles via a free-radical mechanism, whereas the methylthio-analogs afford arylthiomethyl iso-propyl carbonates, together with benzothiazoles as well; this last result could be accounted for with the intervention of non-radical mechanism
描述了2-甲硫基-或2-苯硫基芳嘌呤与过氧二碳酸二异丙酯(DPDC)的反应。苯硫基衍生物通过自由基机理环化成苯并噻唑,而甲硫基类似物也提供芳硫基甲基异丙基碳酸酯,以及苯并噻唑。最后的结果可以由非激进机构与激进机构并排运行的干预来解释。
