(BROMOMETHYLENE)DIMETHYLIMINIUM BROMIDE Usage And Synthesis

Uses

(Bromomethylene)dimethyliminium bromide (bromodi- methylformiminium bromide) may be employed for the synthesis of 6-phenyl-6-deoxy-2,3-di-O-methylcellulose.

General Description

(Bromomethylene)dimethyliminium bromide participates in one-carbon homologation of aldehydes to carboxylic acid derivatives.

Synthesis

Dimethylbromomethyleneammonium Bromide can be synthesized by adding Phosphorus(III) Bromide slowly to DMF in chloroform. It is more reactive than the bromide salt, which has been accounted for by a rapid exchange of the bromide and dibromophosphate anions.

Precautions

(Bromomethylene)dimethyliminium bromide is corrosive, air-sensitive, and lachrymatory, and must be treated with caution.
