2-Naphthol underwent Friedel-Crafts reaction with Nbenzyloxycarbonylamino sulfones in the presence of InCl 3 at room temperature to form the corresponding sulfonyl derivatives in high yields. The products were subsequently reacted with nucleophiles such as allyltributyltin and anisole to replace the sulfonyl group.

[(Tosylamino)alkyl]naphthalenols have efficiently been synthesized by nucleophilic addition of naphthalen-2-ol with N-tosyl imines (derived from both aromatic and aliphatic aldehydes) in the presence of BF 3 · OEt 2 as a catalyst at room temperature. The products are formed within 5 -9 h in high yields (72 -91%).
