addition of sodium peroxide and aqueous NH4OAc solution effected oxidation to afford aryl heteroaryl ketones in good yields. Aryl acetonitrile derivatives are thus umpolung-type synthons of the corresponding aryl carbonyl functionality.
2-芳基乙腈衍生物的阴离子与各种杂芳基氯化物或溴化物在S N Ar歧管中反应,得到易于氧化的中间阴离子。加入过氧化钠和NH 4 OAc水溶液进行氧化,以高收率得到芳基杂芳基酮。因此,芳基乙腈衍生物是相应的芳基羰基官能度的umpolung型合成子。
