O- and N-Alkylsubstituted 2-(2′-Hydroxyphenyl)-benzimidazoles and -1,3,4-Oxadiazoles as Complexing and Extracting Agents for Copper-II-Ions2-(2′-Alkoxyphenyl)-benzimidazoles 1, 1-alkyl-2-(2′-hydroxyphenyl)-benzimidazoles 2, 2-(2′hydroxy-4′-alkoxyphenyl)-benzimidazoles 3, 2-(2′,4′-dialkoxyphenyl)-benzimidazoles 4 and 1-alkyl-2-(2′-hydroxy-5′-nitrophenyl)-benzimidazoles 7 are synthesized by condensation of 2-hydroxybenzoic acid derivatives and o-phenylenediamine or its derivatives. Alkyl chains C4, C8 or C12 are introduced by alkylation before or after the ring closure in order to increase the solubility of the reagent in toluene or n-octane. Furthermore the extraction properties of the benzimidazoles are investigated. Also some new analogous compounds of the benzothiazole and the 1,3,4-oxadiazole series were synthesized.
