Applicazioni

Diethylene glycol dimethyl ether is used as a solvent in organic reactions due to its stability towards higher pH and its high boiling point. It is particularly involved in reactions utilizing organometallic reagents such as Grignard reactions and metal hydride reductions. It is also a solvent for hydroboration reactions with diborane.

Note

Hygroscopic. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.

Letteratura

Aprotic solvent which has useful solvent power, e.g. for Sodium borohydride, 35788, and hence has been widely used for in situ generation of diborane and for many other hydride reactions. For use in the hydroboration of olefins with borane-triethylamine complex, see: Org. Synth. Coll., 7, 427 (1990).
