[P4444][Benoxa] ionic liquid was discovered to be very effective for the synthesis of benzothiazoles via cyclization of 2-aminothiophenols with CO2 and hydrosilanes at ambient conditions, and a series of benzothiazoles were obtained in high yields.
A novel method for synthesis of mono-, bis- and tris-benzothiazoles using [(APTDP)(FeCl4)2@HNT] as a green and reusable catalyst under solvent-free conditions is reported.
In this study, a new method for synthesizing 2-methylbenzothiazole derivatives was developed through a multi-component tandem reaction of 2-iodoaniline/1-iodo-2-nitrobenzene, CaC2, and H2S.
A CuI-catalyzed, one-pot, three-component reaction of benzaldehydes, 2-aminobenzothiol and malononitrile is described, wherein CuI plays an electron relay. The method features simplified operation, highly atom economy, and mild reaction conditions.
The central aim of this investigation was to innovate a novel nanocatalyst for the eco-friendly synthesis of benzothiazoles through an acceptorless dehydrogenative coupling of 2-aminothiophenol and benzyl alcohol, mitigating environmental impact.
