A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 16112-21-3, Name is 2-(4-Methylphenyl)benzothiazole, molecular formula is C14H11NS. In a Article，once mentioned of 16112-21-3, Formula: C14H11NS
Copper-catalyzed one-pot three-component reactions of 2-iodoanilines, aldehydes, and NaSH·n H2O afford benzothiazoles in good yields. When CuCl was employed as a catalyst in the absence of a ligand, a variety of aromatic aldehydes and substituted 2-iodoanilines reacted with NaSH·n H2O to produce the corresponding 2-arylbenzothiazoles in 70-98 % yields. The copper catalyst plays a key role in C-S bond formation between NaSH·n H2O and the aryl iodide that was formed from the condensation of 2-iodoaniline and aldehyde. It was found that NaSH·n H2O functions as a sulfur surrogate and oxidant in the formation of benzothiazole. 2-Iodoanilines, aldehydes, and NaSH·n H2O afford benzothiazoles in a one-pot reaction in the presence of a copper catalyst. The desired products can be obtainedin moderate to good yields. The copper catalyst plays a key role in C-S bond formation between aryl iodides and NaSH·n H2O. Copyright
