Abstract:
A pyridine based ionic liquid with a fluoride counter anion which catalyzes Fischer indole reaction and click chemistry. Methods of preparing the ionic liquid, and methods of utilizing the ionic liquid as a catalyst to synthesize indoles/indolenines and tetrazoles are also provided.

Claim (Index 7):
A method of synthesizing the ionic liquid of  claim 1 , the method comprising:\n reacting a pyridine compound of formula (IV) or a salt thereof, a solvate thereof, a stereoisomer thereof, or a mixture thereof with an alkyl halide of formula (V) or a salt thereof, a solvate thereof, a stereoisomer thereof, or a mixture thereof to obtain a N-alkylated pyridinium halide; and\n treating the N-alkylated pyridinium halide with a fluoride salt, thereby forming the ionic liquid of formula (I), wherein:\n R 1  and R 2  are independently selected from the group consisting of an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, and an optionally substituted aryl; \n R 3  is selected from the group consisting of a hydrogen, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, an optionally substituted aryl, an optionally substituted alkoxy, an optionally substituted alkanoyl, an optionally substituted aroyl, a halogen, a nitro, and a cyano; \n R 4  and R 5  are independently selected from the group consisting of a hydrogen, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, and an optionally substituted aryl; \n X is a chloride, a bromide, or an iodide; and \n n is an integer in a range of 0-15.
