English description（英文原文，共 2107 字符）
Product Name:Sodium imidazolide
English Name:Sodium imidazolide
CAS No.:5587-42-8
Aliases:Sodium imidazole salt, Sodium imidazolate
Molecular Formula:C3H3N2Na
Physical Properties:White to off-white crystalline powder, hygroscopic, with a slight characteristic odor. Melting point >300°C (decomposition). Very soluble in water, forming a strongly alkaline aqueous solution; readily soluble in polar organic solvents such as methanol, ethanol, DMSO and DMF; slightly soluble in THF; insoluble in non-polar solvents such as diethyl ether and petroleum ether. Stable under dry, sealed conditions at room temperature; strongly hygroscopic, it dissolves rapidly in water with partial hydrolysis to imidazole and sodium hydroxide. It readily absorbs carbon dioxide from air to form carbonate. It is highly reactive toward electrophiles such as alkyl halides and acyl halides, and should be stored and used under inert gas protection. It is a strong base and can act as a deprotonating reagent; the N-1 anion has strong nucleophilicity and can undergo nucleophilic substitution to introduce the imidazolyl group.
Uses:In organic synthesis, it is used as an imidazolating reagent to react with electrophiles such as alkyl halides, acyl halides and sulfonate esters, efficiently producing N-alkylimidazoles, N-acylimidazoles and other derivatives. It also serves as a strongly basic nucleophilic reagent in deprotonation, nucleophilic substitution and condensation reactions for constructing complex heterocyclic molecules containing imidazole rings. In functional materials, it acts as a precursor to imidazolium-based ionic liquids and as a modifying agent for polymers, enabling the preparation of functionalized ionic liquids and improving the conductivity, coordination ability and thermal stability of polymers.
