(Dichloromethylene)dimethylammonium chloride Chemical Properties,Usage,Production
Chemical Properties
light yellow crystalline powder
Uses
Dichloromethylene-dimethyliminium Chloride is a useful chemical reagent. It has been used in the synthesis of 12-deoxychlorovulone II analogs via chloride nucleophilic substitution reaction catalyzed by Viehe''s salt.
Uses
Dichloromethylene-dimethyliminium chloride was used as reagent in the synthesis of selenourea and (R)-2-(2-chloroethyl)pyrrolidine-1-carboxylic acid ethyl ester. It was used for introducing amide chloride group into activated substrates.
Uses
Chlorinating agent; introduces amide chloride groups into activated substrates. Building block in organic synthesis.
General Description
Dichloromethylene-dimethyliminium chloride (Vilsmeier reagent) reacts with o-acetaminophenols under Meth-Cohn conditions to yield 2-formylpyrido[2,1-b]benzoxazoles.
