1,1-Dichlorodimethyl ether Chemical Properties,Uses,Production

Chemical Properties

Colorless liquid

Uses

Common formylating reagent for aromatic compounds, chlorinating agent for carboxylic acids, and reactant with borinic esters for the preparation of alkenones.

Reactivity Profile

Carbon monoxide equivalent in reactions with boranes and borinates; formylating reagent for aromatic compounds and vinylsilanes; formation of α-keto acid chlorides

Synthesis

1,1-Dichlorodimethyl ether is prepared from Methyl Formate and Phosphorus(V) Chloride.

Precautions

Dichloromethyl methyl ether is moisture sensitive, a lachrymator, and a suspect carcinogen. Handle in a fume hood.
