Contrary to an earlier report, the interaction of BF3 with SnCl3− or GeCl3− does not lead to the formation of simple complexes such as Cl3SnBF3. The reaction which does occur may be described as Cl− transfer from a weak Lewis acid, MCl2 (M = Sn or Ge), to a stronger Lewis acid, BF3; viz SnCl3− + BF3 = SnCl2 + BF3Cl−.
相反,先前的一份报告,BF的相互作用3用的SnCl 3 -或GeCl 3 -不会导致简单的络合物,如
氯的形成3 SnBF 3。这确实可被描述为
氯发生反应-从弱
路易斯酸转移,中号
氯2(中号= Sn或Ge)的,到一个更强的
路易斯酸,BF 3 ; 即的SnCl 3 - + BF 3 =的SnCl 2 + BF 3
氯-。
