Description

2,4,6-Trimethylpyridinium p-toluenesulfonate is a carbonyl reagent that can be used to synthesize β-unsaturated ketones. It is prepared by the reaction of 2,4,6-trimethylpyridine with p-toluenesulfonic acid in diethyl ether and an acid catalyst. The compound is soluble in benzene and diethyl ether but insoluble in water. 2,4,6-Trimethylpyridinium p-toluenesulfonate has a viscosity of 1.1 cPs at 25°C and a melting point of 180°C. This compound can be used as a reagent for the preparation of β-unsaturated ketones from carbonyl groups.
