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.

Glymes (i.e. glycol diethers) were explored as alternative benign solvents for enzymatic reactions, specifically the lipase-catalyzed transesterification. Long-chain glymes were found highly compatible with immobilized Candida antarctica lipase B (iCALB), leading to higher enzyme activities and stabilities than t-butanol and

The physical content of and, in particular, the nonlinear contributions from the Langevin-Debye model are illustrated using two applications. First, we provide an improvement in the Langevin-Debye model currently used in some implicit solvent models for computer simulations of solvation
