REGIOSELECTIVE ONE-POT SYNTHESIS OF 2-ARYL-6-BROMOBENZOTHIAZOLE FROM ARYLALDEHYDE AND 2-AMINOTHIOPHENOL WITH PHENYLTRIMETHYLAMMONIUM TRIBROMIDE IN THE PRESENCE OF A CATALYTIC AMOUNT OF ANTIMONY(III) BROMIDE

[摘要]：Various 2-aryl-6-bromo-1,3-benzothiazoles were regioselectively afforded in good yields by the reaction of arylaldehydes and 2-aminothiophenol with phenyltrimethylammonium tribromide in the presence of a catalytic amount of SbBr(3) in CH(2)Cl(2) at room temperature.
