Polyfluoroalkyl iodides could react with unsaturated olefin acids in the presence of sodium dithionite by radical addition to give adducts. It was found that these adducts could form polyfluoroalkyl substituted γ or δ-lactones due to intramolecular nucleophilic substitution in the alkali solution.

研究发现：多氟烷基碘化物在连二亚硫酸钠存在下与不饱和烯酸经自由基加成得到的产物，能在碱性条件下进行分子内亲核取代反应形成五元或六元环的含氟内酯类化合物。

He promoted more members of minorities than any previous president; and he also stood up to the Dixiecrat wing of his party, edging Trent Lott, a Mississippi senator, out of his job as majority leader for segregation-favouring remarks.

他比任何前任总统提拔了更多的少数族裔。他也勇敢面对了党内的分裂分子。其中以密西西比州参议员特伦特？洛特为尤甚，他最终因倡导支持种族隔离而下台。
