Bromodimethylsulfoniumbromide acts as an efficient catalyst for one pot three component condensation reactions of aldehydes, 2-naphthol, and thiols in acetonitrile at room temperature. Various aliphatic and aromatic thiols undergo conjugate addition with in situ generated enone in acetonitrile and provide good yields. The main features of this procedure are mild reaction conditions, good yields, and

unsymmetrical ether derivatives1-(alkoxy(aryl)methyl)naphthalen-2-ols (3a–q) were synthesized from 1-(aryl(alkyl/arylthio)methyl)-naphthalene-2-ol derivatives (1) and alcohols (2) by cleavage of C–S bond using bromodimethylsulfonium bromide (BDMS) at room temperature. Moreover, 1-(hydroxy(aryl)methyl)naphthalen-2-ol derivatives (7a–d) were also synthesized from the corresponding sulfide derivatives (1) on reaction
