WebAbstract Abstract : Thirteen compounds of 3-substituted phenols were nitrated by lanthanide(III) nitrates in a solution of ethyl acetate. Whether the substituents were ortho-, para-directing groups or meta-directing groups, only one kind nitrated product, 3-substituted-5-nitropenol, and its intermediate were obtained respectively. Web4-Nitrophenol is an intermediate in the synthesis of paracetamol. It is reduced to 4-aminophenol, then acetylated with acetic anhydride. [6] 4-Nitrophenol is used as the …
