Description

General description

1,2-Dimethoxyethane (DME) is an inert aprotic polar solvent for electrolytes of lithium batteries, polysilicones, oligo- and polysaccharides.

Application

1,2-Dimethoxyethane can be used as a solvent to synthesize:

• Oxazoles from α-acylamino ketones via Robinson-Gabriel reaction.
• 5-Arylhistidines via Suzuki-Miyaura cross-coupling between 5-bromohistidine and arylboronic acids.
• Aryl thioethers via Pd-catalyzed thioetherification of aryl halides with aliphatic and aromatic thiols.
