deprotonation reaction involving its readily prepared pyridinium ion precursor. This donor is able to reduce a variety of aryl halides, and, owing to its redox potential, was found to be the first organic donor to be effective in the thermally induced reductive SN bond cleavage of N,N‐dialkylsulfonamides, and reductive hydrodecyanation of malonitriles.
制备了一种新的基态有机电子给体,其在双吡啶亚烷基骨架上具有四个强烈的π-供电子亚氨基膦酸酯取代基。循环伏安法显示,该对夫妇涉及中性有机供体及其指示,相对于饱和甘汞电极(SCE),记录的氧化还原电势为-1.70V。可以通过涉及易于制备的吡啶鎓离子前体的去质子化反应来分离(44%)这种高还原性有机化合物,或者更方便地就地生成。该给体能够还原各种芳基卤化物,并且由于其氧化还原电位,被发现是第一个对热诱导的N,N还原SN键裂解有效的有机给体。-二烷基磺酰胺和丙二醛的还原性加氢脱氰作用。
