General description
Pyrrolidine is a five membered cyclic amine. It is a nitrogen heterocycle that forms the nucleus of various bioactive molecules. It can be synthesized by reacting 1,4-diaminobutanes with acids. It behaves as a strong base in employed in certain homogeneous nonaqueous reactions. Its crystalline structure has been investigated. Its reaction on the Ge(100)-2×1 surface and Si(100)-2×1 surface has been investigated. Pyrrolidine has been found to be one of the component of volatile amine fraction in the brewing process. A study on the kinetics of pyrrolidinolysis of phthalimide (PTH) shows second- and third-order terms in the rate law. Biodegradation of pyrrolidine by Mycobacterium strains has been studied.
Application
Pyrrolidine may be used in the following studies:
- Synthesis of pyrrolidine derivatives of pyrimidine.
- As a catalyst in the selective monoallylation of allylic alcohols.
- To capture carbondioxide in a bubble column reactor using pyrrolidine aqueous solutions by gas–liquid absorption.

A dual platinum- and pyrrolidine-catalyzed direct allylic alkylation of allylic alcohols with various active methylene compounds to produce products with high monoallylation selectivity was developed. The use of pyrrolidine and acetic acid was essential, not only for preventing undesirable side

Nine bacterial strains that grew on morpholine and pyrrolidine as sole carbon, nitrogen, and energy sources were isolated from three different environments with no known morpholine contamination. One of these strains could also degrade piperidine. These bacteria were identified as
