2,4,6-TRIMETHYLPYRIDINIUM P-TOLUENESULFONATE Usage And Synthesis

Chemical Properties

White powder

Uses

2,4,6-Trimethylpyridinium p-toluenesulfonate may be used in chemical synthesis, as acid catalyst in acetalization, transacetalization, macrolactonization, and conversion of enynones to phenols.

Preparation

2,4,6-Trimethylpyridinium p-toluenesulfonate can be prepared by the slow addition of p-Toluenesulfonic Acid in methanol to a rapidly stirred solution of 2,4,6-Collidine in diethyl ether, at 20 °C. Cooling to 0 °C results in crystallization of the title reagent.

storage

store in desiccator under nitrogen. Very good shelf life at room temperature when kept dry. Irritant; handle with gloves.

Purification Methods

recrystallization from acetone
