title: The regiospecific Fischer indole reaction in choline chloride.2ZnCl2 with product isolation by direct sublimation from the ionic liquid.
abstract: The Fischer indole synthesis occurs in high yield with one equivalent of the ionic liquid choline chloride[middle dot]2ZnCl(2); exclusive formation of 2,3-disubstituted indoles is observed in the reaction of alkyl methyl ketones, and the products readily sublime directly from the ionic liquid.
