the antibacterial activity of a series of ionic liquids containing short-chained 1-alkyl-3-methylimidazolium cations ([cnmim+]; n = 2, 4, 6 and 8) and bis (trifluoromethylsulfonyl) imide anion ([tf2n]) against e. coli and b. subtilis was measured, for the first time. all ils used in this work were synthesized and analyzed by fourier transform infrared (ft-ir) spectroscopy, nmr, and karl-fischer...

para-aminobenzoic acid is supported on silica gel via reaction of activated silica gel and p-aminobenzoic acid which is then converted to its manganese and cobalt salts. a mixture of the manganese and cobalt salts of the acid is used to catalyze allylic and benzylic alcohols to their corresponding carbonyl compounds in reasonable yields using oxygen or air. reactions are clean and the catalysts...
