Bucherer反应（布赫尔反应，Bucherer reaction），又称Bucherer–Lepetit反应

萘酚在亚硫酸氢钠存在下与氨作用，转变成相应的萘胺。

这个反应最早是由法国化学家 R. Lepetit 在1898年发现的，此后德国化学家 Hans Theodor Bucherer (1869－1949) 在1904年又独立发现此反应，发现了其可逆性，并将其应用到化学工业中。目前这个反应一般是称作 Bucherer 反应，但也有称作 Bucherer-Lepetit 反应或 Bucherer-Le Petit 反应（错误名称）。

The Bucherer reaction in organic chemistry is the reversible conversion of a naphthol to a naphthylamine in the presence of ammonia and sodium bisulfite. The reaction is widely used in the synthesis of dye precursors aminonaphthalenesulfonic acids.

The French chemist Robert Lepetit was the first to discover the reaction in 1898 but it was the German chemist Hans Theodor Bucherer (1869–1949) who discovered (independent from Lepetit) its reversibility and its potential especially in industrial chemistry. Bucherer published his results in 1904 and his name is connected to this reaction. The organic reaction also goes by the name Bucherer-Lepetit reaction or (wrongly) the Bucherer-Le Petit reaction.
