BF3.OEt2 and TMSOTf: A synergistic combination of Lewis acids.
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.
