(Dichloromethylene)dimethylammonium chloride Usage And Synthesis

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.
