In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The reduction of pyridine derivatives with lithium aluminum hydride, published in 1953, which mentions a compound: 1195-58-0, mainly applied to , HPLC of Formula: 1195-58-0.
When pyridine derivatives (I) with CO2Et or CN groups at the 3- and 5-positions are treated with LiAlH4 (II) the ring system is attacked first; when the 2-, 4-, and 6-positions are substituted, the functional group are reduced. The reductions are carried out by adding a large excess of II in ether to the I in absolute ether with stirring and ice-cooling, treating the mixture with saturated NH4Cl solution, and evaporating the washed ether solution Reduction of 5 g. di-Et 2,6-lutidine-3,5-dicarboxylate in 50 cc. ether with 780 mg. II in 40 cc. ether gives 40% Et 3-hydroxymethyl-2,6-lutidine-5-carboxylate, m. 100-1°; when the mixture is refluxed 2 hrs. 65% 3,5-bis(hydroxymethyl)-2,6-lutidine, m. 141-2°, is obtained. Reduction of di-Me dinicotinate gives 50% di-Me 1,4-dihydrodinicotinate, m. 150-60°, λmaximum 220, 375 mμ (MeOH). Reduction of di-Me 2-methyl-dinicotinate also gives a dihydro derivative, b0.02 115-20°, yellow needles, m. 126°, λmaximum 220, 375 mμ (MeOH). Reduction of 10 g. 2-chloropyridine (III) with 1 g. II at 0° gives unchanged III. Reduction of 1 g. Et picolinate gives 2-pyridine methanol (picrate m. 159°). Reduction of Et 2-pyridyl-acetate gives 2-pyridineëthanol, b15 120° (picrate, m. 120°). Refluxing 50 g. dinicotinic acid with 150 cc. SOCl2 15 hrs. and treating the acid chloride with NH4OH give 26 g. diamide, m. 302°, which, warmed in 130 cc. C5H5N with 19 cc. POCl3 3 hrs at 60°, yields 15 g. dinitrile (IV), m. 113° after sublimation at 70°/1 mm. Reduction of 1 g. IV in 20 cc. ether with 300 mg. II in 10 cc. ether gives 1,4-dihydrodinicotinonitrile, yellow crystals, m. 197°, λmaximum 360 mμ (MeOH). Similar reduction of 0.43 g. 2,6-lutidine-3,5-dicarbonitrile gives the 1,4-dihydro derivative, yellow crystals, m. 225°, λmaximum 362.5 mμ (MeOH). Catalytic hydrogenation of 0.5 g. IV in 20 cc. MeOH 3 hrs. with 50 mg. PtO2, 0.5 g., gives a dihydro derivative with λmax. 360 mμ which reduces neutral AgNO3. Adding (0.5 hr.) 6.5 g. II in 300 cc. ether to 46 g. Me nicotinate in 300 cc. ether at 0°, decomposing the mixture with NH4Cl, and distilling the residue of the ether extract give 31.3 g. 3-pyridine methanol, b0.1 110° (picrate, m. 158-60°). The difference in the behavior of the pyridine esters and nitriles toward II is explained as resulting from the different polarization of the pyridine rings in these compounds
There is still a lot of research devoted to this compound(SMILES：N#CC1=CC(C#N)=CN=C1)HPLC of Formula: 1195-58-0, and with the development of science, more effects of this compound(1195-58-0) can be discovered.
