Abstract
An novel intermediate of (4-Iodo-phenyl)-(4-trifluoromethyl-phenyl)-diazene for azobenzene liquid crystal was synthesized. 4-Trifluoromethyl-phenylamine as raw material was oxidized by Oxone (Potassium peroxymonosulfate) in CH2Cl2/H2O solvent to synthesize 1-Nitro-4-trifluoromethyl-benzene (m1). The effect of Oxone amount on the conversion degree of raw material was discussed in ditail. Then m1 was coupled with 4-Iodo-phenylamine to obtain the important intermediate, yellow solid, the yield was 52%. The chemical structures of synthetic intermediate was confirmed by FT-IR and 1H-NMR.
