應用
1-Methylimidazole can be used as an organocatalyst to synthesize:
It can also be used as:
- 4-amino-3,5-dicyano-6-arylphthalates via one-pot, a three-component reaction between arylidenemalononitriles, dialkyl acetylenedicarboxylates, and malononitrile.
- Aromatic and aliphatic carbamates from hydroxamic acids via the Lossen rearrangement.
- Tetrahydrobenzo[b]pyrans via three-component cyclocondensation reaction between aromatic aldehydes, malononitrile, and dimedone.
It can also be used as:
- A co-catalyst in copper-catalyzed, greener oxidation of alcohols to carbonyl compounds under aerobic conditions.
- A solvent/complexing agent in the preparation of CuInS2 n-type semiconductive particles.
- A co-additive in the synthesis of acid-sensitive epoxides by methyltrioxorhenium-catalyzed epoxidation of alkenes with H2O2.

An effective method for suppression of ring opening and rearrangement of acid-sensitive epoxides during methyltrioxorhenium(MTO)-catalyzed epoxidation of alkenes with H(2)O(2) by using 1-methylimidazole as a co-additive has been found. The combined use of 3-methylpyrazole and 1-methylimidazole as the additives has

Cu/TEMPO catalyst systems promote efficient aerobic oxidation of sterically unhindered primary alcohols and electronically activated substrates, but they show reduced reactivity with aliphatic and secondary alcohols. Here, we report a catalyst system, consisting of ((MeO)bpy)Cu(I)(OTf) and ABNO ((MeO)bpy = 4,4'-dimethoxy-2,2'-bipyridine;
