Several new boron compounds containing the 2,4,6-(CF3)3C6H2 (fluoromes = Ar), 2,6-(CF3)2C6H3 (fluoroxyl = Ar′) or 2,4-(CF3)2C6H3 (Ar″) ligands have been synthesised from reactions of ArLi, Ar′Li or Ar″Li with BCl3, and characterised by 19F and 11B NMR spectroscopy. Chlorine/fluorine exchanges are evident in these reactions. The crystal and molecular structures of Ar2BF, Ar″3B, Ar2B(OH), Ar′B(OH)2 and
几种含有2,4,6-(CF 3)3 C 6 H 2 (氟代= Ar),2,6-(CF 3)2 C 6 H 3 (氟代= Ar')或2,4的新型硼化合物-(CF 3)2 C 6 H 3 (Ar'')配体由ArLi,Ar'Li或Ar''Li与BCl 3的反应合成,并通过19 F和11 B NMR光谱表征。在这些反应中,氯/氟的交换是明显的。AR的晶体和分子结构2 BF中,Ar“ 3 B,氩2 B(OH),Ar'B(OH)2和MES 2 BF(MES = 2,4,6-ME 3 c ^ 6 ħ 2)具有通过单晶X射线衍射确定。Ar“ 3 B表示包含三个Ar”的化合物的第一个例子配体在结构上加以表征。在理论的HF / 6-31G *水平上已经计算出了几种新的硼化合物的分子几何结构和GIAO-NMR位移,并与可用的实验结果进行了比较。
