Full TextAbstract
Cyclocondensation of 2-[bis(methylthio)methylene]malononitrile and 2-amino-benzenthiol afforded 2-(benzo[ d ]thiazol-2-yl) malononitrile. This compound, on treatment with phosphorus pentasulfi de, gave the corresponding thioamide derivative in a regioselective manner. Reaction of this compound with several α -bromocarbonyl compounds gave new 2-[( E )-(benzo[ d ]thiazol- 2(3 H )-ylidene)(cyano)methyl]thiazoles.
