Applicazioni

1,3-Dimethyl-2-imidazolidinone is used as a high-boiling polar aprotic solvent. It is used as a substitute solvent for toxic hexamethylphosphoramide. It finds application in detergents, dyestuffs, electronic materials and in the manufacture of polymers. It is involved in the preparation of 1,2-bis(trimethylsilyl)benzene. Further, it is utilized as a solvent during alfa-regioselective prenylation of imines. In addition to this, it constitutes the mobile phase during size-exclusion chromatographic analysis of cellulose.

Note

Hygroscopic. Incompatible with strong oxidizing agents, acid chlorides and phosphorus halides.

Letteratura

High-boiling polar aprotic solvent which has been recommended as a replacement for the carcinogenic hexamethylphosphoric triamide, HMPA. It is stable to alkali metals and strong bases: J. Organomet. Chem., 92, C46 (1975); 117, 149 (1976).

For example, it has been used as a solvent for the displacement of non-activated aryl halides by thiolates: Tetrahedron Lett., 23, 4131 (1982); J. Org. Chem., 44, 2642 (1979); 45, 4376 (1980); and as a superior solvent in the Ullmann aryl ether synthesis: Chem. Lett., 899 (1988).
