Abstract :
The acid ionic liquid 1-methyl-3-(4-sulfobutyl)-1Himidazolium bisulfate [(CH2)4SO4HMIM][HSO4] was an efficient catalyst for the electrophilic substitution of indole with carbonyl compounds to afford the corresponding bis(indolyl)methanes in good yields under ultrasound irradiation. Notable features of this new procedure are shorter reaction times, cleaner reaction profiles, simple experimental and efficient recovery and recycling of the ionic liquid.
