NEW AROMATIC AZOBISETHERS OBTAINED BY CONDENSATION OF SODIUM 4,4'-AZODIPHENOXIDE WITH MONOCHLOROMETHYLATED DERIVATIVES

These last years, 4,4'-dihydroxyazobenzene was largely used at the obt ention of compounds important for their applications. In this paper we present seven new aromatic azobisethers synthesized by condensation o f sodium salt of 4,4'-dihydroxyazobenzene with following monochloromet hylated derivatives: 1-chloro-2-(chloromethyl)benzene, 1-chloro-3-(chl oromethyl)benzene, 1-chloro-4-(chloromethyl)benzene, 1-chloromethyl na phtalene, 2-(chloromethyl)-1H-isoindole-1,3(2H)dione, 2-chloromethyl-1 ,3-dioxolane and diphenylchoromethane. The structural characterization of azobisethers was performed by FTIR, H-1 NMR, UV-visile spectrometr ies and by elemental analysis. A behaviour as crystalline liquids for these compounds is not detected.
