SYNTHESIS OF NEW IMIDAZOLIUM AND BENZIMIDAZOLIUM LONG ALKYL-CHAIN IONIC LIQUIDS WITH POTENTIAL ANTIBIOFOULING ACTIVITY

Development of environmental-friendly antibiofouling compounds is desirable due to concerns on biocides use. Imidazolium and benzimidazolium long alkyl-chain ionic liquids are a class of heterocyclic organic compounds with a wide range of biological activities. A series of imidazolium and benzimidazolium ionic liquids containing long alkyl and polyalkyl chains and different anionic part were prepared in the form of quaternary salts. Using one-step procedure, salts with an alkyl Nsubstituents and Br counter anions were prepared in good yields. The procedure is convenient, mild and generally gives rise to exclusive N-alkylation. In the second step bromide anions were substituted with large inorganic anions. Their chemical and spectral properties were briefly discussed. The proposed potential antibiofouling activity will be tested in near future.
