Merck, 40727-4L, 1,3-Dimethyl-2-imidazolidinone

General description
1,3-Dimethyl-2-imidazolidinone (DMI) is an imidazolidine derivative. It is reported to act as a promoter by minimizing the formation of dialkylation byproducts and accelerating the rate of monoalkylation of γ-butyrolactone. Conversion of CO₂ to form lower alcohols by homogeneous catalytic hydrogenation using DMI as solvent has been investigated.
Application
1,3-Dimethyl-2-imidazolidinone may be used:
As substitute solvent for hexamethylphosphoric triamide (HMPA) in the synthesis of 1,2-bis(trimethylsilyl)benzene.
As solvent during the α-regioselective prenylation of imine.
As component of mobile phase for the size-exclusion chromatographic analysis of cellulose.

Other Notes
Solvent used in various synthetic organic transformations. Studied in the formation of functionally stabilized hydrosilanediyl-transition metal complexes produced photochemically from arylsilanes.
