Polymer-Supported Tribromide as a New Solid Phase and Recyclable Catalyst for the Synthesis of 2-(N-Arylamino)benzothiazoles Under Solvent-Free Microwave Irradiation Conditions was written by Nahakpam, Lokendrajit;Chingakham, Brajakishor S.;Laitonjam, Warjeet S.. And the article was included in Journal of Heterocyclic Chemistry in 2015.Name: N-Phenylbenzo[d]thiazol-2-amine This article mentions the following:
The solid-phase synthesis of 2-(N-arylamino)benzothiazoles I (R1 = H, 4-CH3, 5-CH3, 4-OCH3; R2 = H, 2-CH3, 4-Cl, etc.) was achieved by reacting substituted thioureas with polymer-supported tribromide in high yield under microwave irradiation The method has several advantages such as short reaction time, good yields, and environmentally benign procedure. The catalyst could be recovered conventionally and reused at least four times without loss of its activity. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Name: N-Phenylbenzo[d]thiazol-2-amine).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Name: N-Phenylbenzo[d]thiazol-2-amine
