(DICHLOROMETHYLENE)DIMETHYLAMMONIUM CHLORIDE - Introduction

Phosgene iminium chloride(Phosgene iminium chloride) is an organic compound with the chemical formula COCl(N(CH3)2). It is colorless to yellowish crystals and can be dissolved in organic solvents.

Phosgene iminium chloride are widely used in organic synthesis, especially as reagents for introducing allyl protecting groups. It can undergo nucleophilic substitution reactions with amines, converting amines into allyl amines. In addition, Phosgene iminium chloride can also be used for the synthesis of allyl sulfide compounds, esterification reactions, and the construction of carbon-nitrogen bonds.

The method for preparing Phosgene iminium chloride is to react methylene dimethyl amine with methylene chloride to form methylene dimethyl amine chloride, which is then reacted with ammonium chloride.

For safety information, Phosgene iminium chloride is a toxic compound that is irritating to the skin, eyes and respiratory tract. During use, it is necessary to wear suitable protective equipment and operate in well-ventilated conditions. Avoid skin contact and inhalation. During storage and handling, comply with relevant safety practices and regulations.
