207556-07-8 - Introduction
1-(~ 2 ~ H_3_)methyl-4-phenylpyridinium is an organic compound with many properties and applications. Here is the relevant information:
properties: the chemical formula of 1-(~ 2 ~ H_3_)methyl-4-phenylpyridinium iodide is C15H10D3IN, and the appearance is white crystalline solid. It is insoluble in water at room temperature, but soluble in organic solvents such as chloroform, carbon disulfide and methylene chloride.
Uses: 1-(~ 2 ~ H_3_)methyl-4-phenylpyridinium iodide is widely used in organic synthesis as an important reagent. It can be used as a deuteration reagent for D3-phenyl pyridine iodide for labeling D atoms; It can also be used as a catalyst for iodination, Bromination and chlorination reactions.
Preparation Method: The preparation of 1-(~ 2 ~ H_3_)methyl-4-phenylpyridinium is usually carried out by an iodination reaction. First, benzopyridine was dissolved in anhydrous dichloromethane, and then copper N-methyl-D3-4-phenylmethylenepyridine was dissolved in dichloromethane and slowly added dropwise to benzopyridine. Finally, the filtered powder was added, cooled to room temperature and filtered to give the desired product.
Safety information: 1-(~ 2 ~ H_3_)methyl-4-phenylpyridinium iodide needs to pay attention to safety during operation and storage. It is an irritating substance that can cause inflammation on contact with the skin or eyes. Wear appropriate protective equipment, such as gloves and glasses. At the same time, it should be operated in a well-ventilated place to avoid inhaling its vapor. In the event of contact or inhalation, wash the affected area immediately and seek medical attention if necessary.
