General description
Diethylene glycol dimethyl ether is a hydrophilic electron-donor solvent.
Application
Diethylene glycol dimethyl ether may be used as a solvent in the following processes:
- Synthesis of 3,5-dinitrobenzaldehyde via reduction of 3,5-dinitrobenzoyl chloride using lithium aluminum tri-tert-butoxyhydride.
- Copper-catalyzed cross-coupling of iodoarenes with 4-[2,2,2-trifluoro-1-(trimethylsilyloxy)ethyl]morpholine to form the corresponding trifluoromethyl arenes.
- Conversion of olefins (for eg: (±)-α-pinene) to primary amines (3-pinanamine) via hydroboration-amination reaction.
