Abstract
A new method for the 1,1′-binaphthalene-2,2′-diol and 1,1′-binaphthyl-2,2′-dialkylether by CuCl2 and FeCl3 under solid-state condition and ionic liquid is described. The stereo selectively coupling of 2-naphthol by CuCl2 and FeCl3 in presence of optically active amino acid is also studied. The optically purity of (S)-binaphthalene-2,2′-diol in the presence of L-2-phenylglycine by FeCl3·H2O in solid state and ionic liquid is 41 and 96 %, respectively.
