[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. (BROMOMETHYLENE)DIMETHYLIMINIUM BROMIDE synthesis route
[Precautions]

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