  A simple approach to benzothiazoles from 2-chloronitrobenzene, elemental sulfur, and aliphatic amine under solvent-free and catalyst-free conditions

  摘要：

  A novel solvent-free and catalyst-free synthesis of benzothiazoles from 2-chloronitrobenzene, elemental sulfur, and aliphatic amine has been developed. The reaction tolerated a wide range of functionalities, and various benzothiazoles were synthesized in moderate to good yields in the absence of external oxidant or reductant. (C) 2014 Elsevier Ltd.

  Heating N-(2-methoxyphenyl)benzenecarbothioamides in refluxing nitrobenzene for 24 hours gives the corresponding benzothiazoles with intramolecular ipso substitution of the orthomethoxy substituent. The thermal cyclization of various other N-arylthiobenzamides is also explored.
