sulfides [PhS(CH2)nCH(OH)R] with hexabutyldistannoxane (HBD)–bromine system was studied in order to clarify neighboring group participation during the course of reaction. The oxidation products were found to be highly dependent on the positions of the two functional groups [sulfide and hydroxyl group]. Thus hydroxy sulfoxides [PhSO(CH2)nCH(OH)R] were obtained as the main product when n=1 or 2, bromo sulfones
                                    研究了羟基
硫化物 [PhS(
CH2)nCH(OH)R] 与六丁基二
锡氧烷 (HBD)-
溴体系的氧化,以澄清反应过程中相邻基团的参与。发现氧化产物高度依赖于两个官能团 [
硫化物和羟基] 的位置。因此,当 n=1 或 2 时,主要产物为羟基亚砜 [PhSO(   )nCH(OH)R],当 n=3 或 4 时,主要产物为
溴砜 [PhSO2(   )n
CHBrR]。酮亚砜 [PhSO(    )nCOR]仅在 n=6 时形成。根据两个官能团的位置,根据不同的分子内相互作用来讨论结果。
