Opis

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 HMPA in the synthesis of 1,2-bis(trimethylsilyl)benzene.
• As solvent during the α-regioselective prenylation of imines.
• A component of mobile phase during size-exclusion chromatographic analysis of cellulose.

Other Notes

Aprotic, dipolar solvent which often can be used as a substitute for the carcinogenic HMPA

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