In this work we studied the reactions of benzothiazole sulfones and sulfoxides toward reactive sulfur species. The reaction of thiols with benzothiazole sulfones produces sulfinic acids (RSO2H), which can further react with sulfane sulfurs to form thiosulfonic acids (RSO2SH). This was used to design fluorescent sensors for hydrogen polysulfides. The reaction of thiols with benzothiazole sulfoxides produces sulfenic acids (RSOH), which can undergo fast intramolecular cyclization and be used to design thiol-triggered fluorescent sensors.

This work is a course proposal for a stronger ethics education component for chemistry undergraduates. We propose that this course should integrate different approaches in ethics with the value-laden and scientifically complex issues that arise in chemistry. Although some programs require that students take some ethics as a core requirement, for many it is just an option among many humanities courses. Alternatively, ethics may arise passively during courses devoted primarily to chemistry. For our proposed course to be maximally effective, we believe it should integrate both ethics and chemistry, inviting students to think about complex real-world problems. This allows students to identify ethical considerations in the context of cases they might encounter as part of their careers in chemistry. It would also provide them with resources to identify the best course of action.
