Authors
abstract
a convenient and efficient direct protocol for the preparation of antibacterial azo dyes by the reaction of 2-naphthol with aromatic amines in the presence of catalytic amount of n-methyl-2-pyrrolidonium hydrogen sulfate ([h-nmp]hso4) was carried out under solvent free conditions. this method has some advantages such as: easy work-up and easy separation of catalyst from the reaction mixture. the in vitro antibacterial activities of some compounds were studied using gram positive and negative microorganisms.

Polymer/HIO4 : An efficient catalyst for solvent-free synthesis of 2-naphthol azo dyes
A convenient, one-pot method for the synthesis of diazonium salt has been developed by the sequential diazotization of aromatic amines with NaNO2, polymer- supported periodic acid (PPIA) and 2-naphthole under solvent-free conditions at room temperature. By using this method, several types of aromatic amine, containing electron-withdrawing and electron-donating groups, were rapidly converted to ...
