摘要：

In the presence of water lithium tetrahydroborate is capable of reducing pyridine to 1,4-dihydropyridine. The product, lithiumtetrakis(pyridine) tetrakis(1,4-hydropyridyl)borate, was isolated and characterized by NMR and IR spectroscopy and single crystal X-ray diffraction. [Li(py)(4)][B(pyH)(4)].2(1,4-dioxane) crystallized in space group P4(2)/n, Z = 2. Similarly, NaBH4 can also reduce pyridine in the presence of water and equivalent amounts of LiCl or ZnCl2.
