Application

α-Naphthylamine and sulfanilic acid are used for detection of nitrate reduction by bacteria. Organisms containing nitrate reductase reduce nitrate to nitrite, which forms a diazonium salt with sulfanilic acid and reacts with α-naphthylamine to form a red azo dye.

2-Aryl benzothiazole formation from aryl ketones and 2-aminobenzenethiols under metal- and I(2)-free conditions was described. Various 2-aryl benzothiazoles were selectively obtained in good yields using molecular oxygen as oxidant. DMSO played an important role in this transformation. Functional groups such

Raman scattering measurements were conducted for 4-aminobenzenethiol (4-ABT) assembled on powdered copper substrates. Initially, very weak Raman peaks were detected, but upon attaching Ag nanoparticles probably via NH2 groups onto 4-ABT/Cu, distinct Raman spectra were observed. Considering the fact that
