| Application: | Pyrrolidine can be used as: • A base for the chemoselective reduction of ketones to alcohol in the presence of decaborane and cerium(III) chloride heptahydrate in methanol. • A reactant with benzaldehyde and β-naphthol for the synthesis of betti base using non-ionic surfactant (Triton X-100) as a catalyst. • A catalyst in the synthesis of aldimines from aldehydes and primary amines. • A modifier for aluminum hydride reagent, which is used as a selective reducing agent to transform N-benzyl-4-ethoxycarbonylp • As a solvent/base in palladium-catalyzed Sonagashira coupling reactions. |
