Hexavalent chromium is one of the main heavy metal pollutants. As the environmental legislation becomes increasingly strict, seeking new technology to treat wastewater containing hexavalent chromium is becoming more and more important. In this research, a novel modified ultrafiltration membrane that could be applied to adsorb and purify water containing hexavalent chromium, was prepared by poly...

To develop a new facile protocol for the synthesis of 2'-aminobenzothiazolo-arylmethyl-2-naphthol derivatives, N-bromosuccinimide (NBS) was used as an efficient catalyst for the one-pot synthesis of 2'-aminobenzothiazolo-arylmethyl-2-naphthols in excellent yields from β -naphthol (1 mmol), aromatic aldehydes (1 mmol), and 2-aminobenzothiazole (1 mmol) at 60°C under solvent-free conditions.

The four-component reaction of 2-aminobenzothiazole, aromatic aldehydes, acetylenedicarboxylate and piperidine or pyrrolidine in ethanol afforded the functionalized 2-pyrrolidinones containing both benzothiazolyl and piperidinyl (or pyrrolidinyl) units in good yields. On the other hand, the similar four-component reactions resulted in the functionalized morpholinium or piperidinium 2-pyrrolidin...

Novel copper complexes of 2-aminobenzothiazole derivatives were synthesized by the condensation of knoevengal condensate acetoacetanilide (obtained from substituted benzaldehydes and acetoacetanilide) and 2-aminobenzothiazole. They were thoroughly characterized by elemental analysis, IR, H-NMR, UV-Vis., molar conductance, magnetic moment and electrochemical studies. The UV-Vis., spectral study ...

The three organometallic complexes [(Cis-PtII (DDH) (2,5-Dihidroxibenzensulfonic)2, RhI(CO)2Cl(2-Aminobenzothiazole) and RhI(CO)2Cl(5-Cl-2-Methilbenzothiazole)] used in this study had been previously found to have a high in vitro activity against promastigote and amastigote like forms of Leishmania donovani. Here, the cytotoxic effect of these new organometallic complexes on the J-774 macrophag...

A series of N-{(substituted)1,3-benzothiazol-2-yl}-1,1 '-biphenyl-4-carboxamides was synthesized by reaction between biphenyl acid chloride and 2-aminobenzothiazole. The synthesized compounds were screened in vivo for diuretic activity. Among the series, N-(1,3-benzothiazol-2-yl)-1,1'-biphenyl-4-carboxamide (II) was found to be the most promising candidate.

A mild and efficient one-pot visible light irradiated synthesis of 2-aminobenzothiazole 4(a–l) from arylisothiocyanate 1(a–l) and secondary amines 2 have been reported in presence of eosin Y as an organophotoredox catalyst at room temperature under aerobic condition. This synthesis includes application of air and visible light as inexpensive, readily available, high atom economy, non-toxic and ...

A Ni-catalyzed C-S bond forming reaction has been developed for the synthesis of 2-aminobenzothiazole by the coupling of 2-haloanilines (-bromo and -iodo) with isothiocyanates. The key advantages of this procedure are ligand-free condition, inexpensive catalyst, high yields, and simple purification of the products by nonchromatographic technique.
