DIMETHYLAMINOPHOSPHOROUS DICHLORIDE - Introduction

The phosphonium chloride, also known as dichlorohydrin amine thiophosphine (phosphonium chloride), is an organophosphorus compound. Its chemical formula is (CH3) 2ncl2p.

Properties: It is a colorless to light yellow liquid with a pungent odor. It can be decomposed in water, insoluble in water, but soluble in organic solvents such as alcohols and ethers.

Uses: Mainly used as a catalyst and reagent in organic synthesis reactions. It is commonly used in Friedel-Crafts reactions, gas-solid atomic transfer microscopy imaging, and the addition reactions of alkenes and alkynes.

preparation method: preparation method is generally obtained by the reaction of dimethyl amine and phosphorus chloride. Specific preparation methods can be found in organic synthesis handbooks or related literature.

Safety information: Avoid contact with skin and eyes, which can cause skin burns and eye irritation. Wear appropriate protective gloves and glasses during use to ensure a well-ventilated operating environment. If it comes into contact with skin or eyes, rinse immediately with plenty of water and seek medical advice. In addition, storage should avoid contact with strong oxidants and other substances, and away from fire sources.
