The BF3·OEt2-promoted nucleophilic substitution of α-aryl-α-ketophosphates to afford α,α-diaryl ketone products is described. Electron-rich α-ketophosphates perform best, with electron-neutral and electron-poor substrates also tolerated. The reaction is tolerant of a range of aromatic, heteroaromatic and non-aromatic nucleophiles, with yields ranging from 44-84%. Enantioenriched starting material yields racemic product, suggesting an SN1 pathway via an acylcarbenium ion.
