Applicazioni

1,2-Dimethoxyethane is widely used as a solvent for electrolyte of lithium batteries, polysilicones, oligo- and polysaccharides. It plays an important role in Grignard reactions, Suzuki reactions and Stille couplings in organometallic chemistry and in pharmaceutical synthesis. It is a higher boiling point solvent and is used as an alternative to diethyl ether and tetrahydrofuran. It is used for the etching of synthetic polymers like polytetrafluoroethylene and other fluoropolymers with alkali metal dispersions.

Note

Keep away from sources of ignition. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents. It can be oxidized on air to form peroxides.

Letteratura

Solvent for lithiations and metal hydride reductions.

Recommended solvent for the Schmidt reaction of ketones with hydrazoic acid, avoiding potential hazards reported with the more usual chlorinated solvents, particularly chloroform. The hydrazoic acid is generated in situ from NaN3 and methanesulfonic acid: Tetrahedron, 52, 1609 (1996).
