曼尼希反应(Mannich反应,简称曼氏反应),也称作胺甲基化反应,是含有活泼氢的化合物(通常为羰基化合物)与甲醛和二级胺或氨缩合,生成β-氨基(羰基)化合物的有机化学反应。一般醛亚胺与α-亚甲基羰基化合物的反应也被看做曼尼希反应。反应的产物β-氨基(羰基)化合物称为“曼尼希碱”(Mannich碱),简称曼氏碱。

    本文目的在于研究Mannich反应,合成一个新的化合物,能够在以后的领域中有所应用。本文以邻苯二胺和乳酸为原料反应合成2-乙酰基苯并咪唑;以对亚硫酰氯和二乙醇胺反应合成N,N-二氯乙胺。再以其为原料,与苯并咪唑反应,合成N,N-二-(1-苯并咪唑亚乙基)胺。再以其为原料和前面已经制得的-乙酰基苯并咪唑反应,合成出目标物。

Mannich reaction (Mannich reaction, referred to as the Man's response), also known as amine methylation, is the active hydrogen containing compounds (usually carbonyl compounds) with formaldehyde and secondary amine or ammonia condensation, generate β-amino ( carbonyl) compounds in organic reactions. General aldimine and α-methylene carbonyl compounds have also been seen as Mannich reaction response. Reaction product β-amino (carbonyl) compounds known as "Mannich" (Mannich base), referred to as the Man base. 

    Purpose of this paper is to study the Mannich reaction, synthesis of a new compound can be in the area after application. In this paper, o-phenylenediamine and lactic acid Synthesis of 2 - acetyl benzimidazole; order of thionyl chloride and diethanolamine Synthesis of N, N-dichloro-ethylamine. Then its raw materials, and benzimidazole was synthesized N, N-II - (1 - benzimidazolyl Asia) amine. Then its raw materials and has already been prepared - the acetyl benzimidazole was synthesized from the target.

Manny Mannich reaction, heber reaction (hereinafter mann's reaction), also known as amine methylation reaction, contain lively hydrogen compounds (usually a carbonyl compounds) with formaldehyde and secondary amine or ammonia condensation, generates beta amino carbonyl compounds () organic chemistry reaction. General aldehyde imine with alpha methylene group carbonyl compounds reaction is being viewed also manny heber reaction. Reaction product of beta amino group (carbonyl compounds called "manny) Mannich heber alkali" (hereinafter mann's alkali), alkali.

This paper aims to study Mannich reaction, synthesis of a new compounds, can later in fields found application. Based on adjacent benzene 2 amine and lactic acid as raw material reaction synthesis benzene 2 - acetyl groups and sulfonated; Based on the sulfur carbonyl chlorides and two diethanolamine reaction synthesis N, N - methylene chloride procedures. Again with its as raw materials, and benzene and sulfonated reaction, synthetic N, N - 2 - (1 - benzene and sulfonated and ethyl) amine. Again for raw materials and with its front has made - acetyl groups benzene and sulfonated reaction, the synthesis target objects.
