Y. Kita et al., NONPHENOLIC OXIDATIVE COUPLING OF PHENOL ETHER DERIVATIVES USING PHENYLIODINE(III) BIS(TRIFLUOROACETATE), Chemical communications, (12), 1996, pp. 1481-1482
Phenol ether derivatives (non-phenolic derivatives), 1,3-diarylpropane
s 1a-e, N-benzyl-N-phenethylamines 2a-c and N,N-dibenzylamines 3a-e re
act with a hypervalent iodine reagent, phenyliodine(III) bis(trifluoro
acetate) (PIFA), containing BF3 . Et(2)O in CH2Cl2 to give the biaryl
coupling products 4a-e, 5a-c and 6a-e in good yields.
