Nitro-Methyl Redox Coupling: Efficient Approach to 2‑Hetarylbenzothiazoles from 2‑Halonitroarene, Methylhetarene, and Elemental Sulfur

Abstract

A simple, straightforward, and atom economic approach to 2-hetarylbenzothiazoles starting from 2-halonitroarene, methylhetarene, and elemental sulfur under mild conditions is described. The method is highlighted by the direct redox nitro-methyl reaction for carbon–nitrogen bond formation without an added oxidizing or reducing agent
