4-Pyrrolidinopyridine Structural

What is 4-Pyrrolidinopyridine?

Description

4-Pyrrolidinopyridine is the pyridine derivative. It can be used as catalyst employed in polymerization reactions or Hypernucleophilic acylation catalyst. For example, it can be used as the catalyst for the geometry-selective (E-selective) acylation of tetrasubstituted α, α'-alkenediols. It can also be used as the ligand in metal complexes such as the Chloride and pseudohalide hydride-carbonyl ruthenium(II) complexes.

Chemical properties

white to light brown crystalline mass
