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.
