1-萘硫酚是一种有机硫化合物,化学式为C10H8S。它的另一种同分异构体2-萘硫酚英语2-Naphthalenethiol

合成

[编辑]

1-萘硫酚可由1-碘萘和硫酸铜、过量的乙二硫醇在碱性条件下反应得到,也可以九水合硫化钠作为硫源,在和乙二硫醇的催化下反应制得。[4]

1-萘酚二硫化物用/氯化铵乙醇中回流,可以将其还原为1-萘硫酚。[5]1-萘磺酰氯在1,2-二氯乙烷中与二甲基二氯硅烷和N,N-二甲基乙酰胺反应,经还原,也能得到1-萘硫酚,副产物二硫化物仅占痕量。[6]其它方法还有1-溴萘甲硫醇钠反应、[7]1-氯萘在600 °C和硫化氢反应[8]等。

性质

[编辑]

1-萘硫酚的化学性质体现在其巯基上,如在碱性条件下和有机卤化物反应生成硫醚。如碱为氢氧化钠时,和2-氯乙醇反应,生成2-(1-萘硫基)乙醇;[9]碱使用碳酸钠,在N,N-二甲基甲酰胺中和溴化苄反应,生成1-萘基苄基硫醚;[10]和邻二卤苯反应则发生成环反应。[11]它和4-二甲氨基苯基氯化锌发生偶联反应,脱硫后生成N,N-二甲基-4-(1-萘基)苯胺。[12]
