Description

General description

1-Methylimidazole is an N-donor ligand generally used in the preparation of coordinate complexes.

Application

1-Methylimidazole may be used as a starting material to synthesize:
• 1-(2-hydroxypropyl)-3-methylimidazolium salts used as ionic liquids
• 1,3-dimethylimidazoyl-2-ylidene borane, a stable and easy to handle N-heterocyclic carbene borane
• It can act both as a catalyst and a solvent in the synthesis of aldononitrile acetates from aldoses.
