This paper reports advances in redox transmetalation/protolysis (RTP) utilizing the readily available Ph3Bi for the synthesis of a series of barium metal-organic species. On the basis of easily available starting materials, an easy one-pot procedure, and workup, we have obtained BaL2 compounds (L = bis(trimethylsilyl)amide, phenyl(trimethylsilyl)amide, pentamethylcyclopentadienide, fluorenide, 2,6
本文报道了利用现成的Ph 3 Bi合成一系列钡金属-有机物种在氧化还原金属转移/质子水解(RTP)方面的进展。根据容易获得的原料,简单的一锅操作方法和后处理方法,我们获得了BaL 2化合物(L =双(三甲基甲硅烷基)酰胺,苯基(三甲基甲硅烷基)酰胺,五甲基环戊二烯,氟化物,2,6-二-如NMR测定所确定的,通过在过四氢呋喃中用三苯基铋和HL超声处理过量的钡金属,定量地定量得到异丙基苯酚和3,5-二苯基吡唑酸酯)。转化率受p K a的影响和大量的HL。Ba与HL的直接反应产生了竞争,从而提高了总转化率,对于体积较小,酸性较大的配体而言,效果尤为明显。总体而言,该方法显着增加了钡金属-有机/有机金属化合物的合成军械库。
