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.[2] 
• As solvent during the α-regioselective prenylation of imine.[1]
• As component of mobile phase for the size-exclusion chromatographic analysis of cellulose.[3]

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.[4] Conversion of CO2 to form lower alcohols by homogeneous catalytic hydrogenation using DMI as solvent has been investigated.[5]
