2-Cyano-4-methylpyridine（CAS# 1620-76-4) Faamatalaga
| Fa'atatauga | O le 2-cyano-4-methylpyridine o se vailaʻau faʻale-aganuʻu, lea e mafai ona muamua faʻamaʻiina mai le 4-methylpyridine e saunia ai le 4-Methyl-pyridine-N-oxide, ona sui lea i le cyano group e maua ai. 4-methyl-pyridine-N-oxide e mafai ona faʻaaogaina e saunia ai le 4-methyl -2, 6-dicarboxypyridine, 4-methyl -2, 6-dicarboxypyridine o se pyridine e sili ona aoga ma o se mea faʻapitoa taua tele, lea e faʻaaogaina lautele. i le matata o fale talavai. |
| sauniuniga | 4-methyl-pyridine-N-oxide (0.109g,1mmol), trimethylcyanosilane (0.119g,1.2mmol), H-diethyl phosphite (0.276g,2mmol), carbon tetrachloride (0.308g,2mmol), triethylamine (0.202g, 2mmol) ma le acetonitrile 10mL ile 50mL fagufagu-gutu tolu, tali i le vevela potu mo le 6h. A maeʻa le tali, e aveese le solvent i lalo o le faʻaitiitia o le mamafa ma tuʻueseese e le koluma chromatography (petroleum ether / ethyl acetate, V / V = 4: 1) e maua ai le faʻaogaina o le vai e leai se lanu ma 80% fua. |
