The reactions of the organotin chlorides RnSnCl4−n(R = Me or Ph; ⩽ n ⩽ 4) with the Lewis acids SbCl5 and BCl3 have been investigated by 119Sn and (where appropriate) 11B NMR spectroscopy. The results show that transfer of organo-groups to antimony or boron usually takes place rather than chloride abstraction to give cationic tin(IV) species, and this process is more facile for phenyl than methyl groups
的有机锡氯化物的反应中[R Ñ的SnCl 4- Ñ(R = Me或Ph值;⩽ Ñ ⩽4)用Lewis酸的SbCl 5和BCL 3由已经研究119 Sn和(适当的)11乙NMR光谱。结果表明,通常发生有机基团向锑或硼的转移,而不是提取氯化物以生成阳离子锡(IV)物种,并且该过程对苯基的作用比对甲基的作用更容易。在某些情况下,通过分离非挥发性反应产物可以证实这些结论。
