The combination of BF3·OEt2 and TMSOTf gives BF2OTf·OEt2, which is a more powerful Lewis acid than its components and especially effective in CH3CN solvent; the complex formed has been characterised by 1H, 19F, 11B and 31P (using Et3PO as an additive) NMR spectroscopy.
BF3·OEt2和TMSOTf的结合生成了BF2OTf·OEt2,这是一种比其组成成分更强的
路易斯酸,在CH3CN溶剂中尤其有效;所形成的络合物已通过1H、19F、11B和31P(采用Et3PO作为添加剂)NMR光谱进行了表征。
