Phenol Derivatives

A variety of phenol derivatives were successfully nitrated via combination of Al(NO3)3·9H2O and silica sulfuric acid in the presence of wet SiO2 (50% w/w) in dichloromethane at room temperature with moderate-to-good yields.

A convenient method for the synthesis of 2-arylbenzothiazoles from condensation of aromatic/heteroaromatic aldehydes with 2-aminothiophenol has been developed using inexpensive, green and reusable solid acids – silica sulfuric acid (SSA), oxalic acid or AlCl3·6H2O as efficient catalysts. The reactions occurred under mild conditions to afford the corresponding 2-arylbenzothiazoles in good to excellent yields.
