Non-Phenolic Oxidative Coupling of Phenol Ether Derivatives Using Phenyliodine(III)bis(trifluoroacetate).

Phenol ether derivatives (non-phenolic derivatives), 1,3-diarylpropanes 1a–e, N-benzyl-N-phenethylamines 2a–c and N,N-dibenzylamines 3a–e react with a hypervalent iodine reagent, phenyliodine(III) bis(trifluoroacetate)(PIFA), containing BF3·Et2O in CH2Cl2 to give the biaryl coupling products 4a–e, 5a–c and 6a–e in good yields.
