Abstract The easily accessible 2-(chloroseleno)benzoyl chloride has broad application in the synthesis of benzizoselenazol-3(2H)-ones and benzo[b]selenophen-3(2H)-ones. Treatment of 2-acylbenzo[b]selenophen-3(2H)-ones with nitrogen nucleophiles such as hydrazines and hydroxylamine resulted in formation of 2-substituted 3-hydroxybenzo[b]selenophenes in 72–98% yield.
摘要 易得的2-(氯硒代)苯甲酰氯在苯并硒唑-3(2H)-酮和苯并[b]硒酚-3(2H)-酮的合成中具有广泛的应用。用氮亲核试剂(如肼和羟胺)处理 2-酰基苯并[b]硒酚-3(2H)-酮,以 72-98% 的产率形成 2-取代的 3-羟基苯并 [b] 硒酚。
