Abstract

When we examined the reaction of magnesium metal with ethyl iodide in imidazolium based ionic liquid [bmim][BF 4 ] (1a), there was no reaction whatsoever, as expected. When [bdmim][BF 4 ] (1b) was used instead so that the acidic proton in the imidazolium moiety was replaced with a methyl group, a colour change from colorless to green and then red was observed at 80 °C. The reaction mixture however reverted to a colourless solution when the ...
