4-Methoxypyridine N-oxide is a heteroaromatic N-oxide used as a nucleophilic catalyst in oligonucleotide synthesis and free radical polymerization.
| [Synthesis]
In a 25-mL round-bottomed two-necked flask, 4 mL of methanol was added, followed by 4-methoxypyridine (0.5 mmol, 54.6 mg), 30% H2O2 (6.0 eq., 0.3 mL), potassium carbonate (4.0 eq., 276.4 mg), and SO2F2 gas was introduced into the gas stream by using two s |
