N-phenylanilinium trifluoromethanesulfonate - Introduction

The chemical formula is [(C6H5)2NH2]2SO3, also known in chemistry as DAST(diarylamine sulfate trioxide). The following is a description of the properties, uses, preparation and safety information of the compound:

1. Properties: Diphenylammonium Trifluoromethanesulfonate is a white crystalline solid, soluble in organic solvents such as toluene and dichloromethane, but almost insoluble in water. It has strong electron acceptor properties and oxidation ability.

2. Use: Diphenylammonium Trifluoromethanesulfonate is widely used in the field of organic synthesis. It can be used as a strong oxidant and fluorination agent, and is usually used in fluorination reaction, sulfonation reaction and chlorination reaction in organic synthesis. It can efficiently introduce fluorine atoms, sulfo groups or chlorine atoms in certain chemical reactions to achieve specific chemical transformations.

3. Preparation method: The preparation method of Diphenylammonium Trifluoromethanesulfonate is more complicated, and is generally completed by a multi-step reaction. First, aniline is reacted with trifluoromethanesulfonic acid to form an aniline salt of trifluoromethanesulfonic acid. This salt is then reacted with sulfuric acid to give Diphenylammonium Trifluoromethanesulfonate.

4. Safety Information: when using Diphenylammonium Trifluoromethanesulfonate, it is necessary to strictly abide by the safety operation regulations. It is irritating and may cause irritation to the eyes, skin and respiratory tract. Wear appropriate protective equipment during operation to avoid contact with skin, eyes and respiratory tract. At the same time, its flammability and explosive need to be paid attention to, should be away from open flames and other flammable materials.
