DOI: 10.1021/acs.orglett.8b02387
Abstract: Herein, the first elemental sulfur-promoted aerobic dehydrogenative aromatization of cyclohexanones is described that provides novel access to synthetically useful o-arylenediamines. This protocol complements previous palladium- and iodine-catalyzed diarylamine formation from cyclohexanones and anilines. read more here.

DOI: 10.1055/a-1430-5100
Abstract: This study aims to develop green and sustainable advanced synthetic methods based on redox cyclization. Elemental sulfur has been shown to promote the efficient synthesis of 2-substituted benzothiazoles from 2,2’-dinitrodiphenyl disulfides and benzylamines via redox… read more here.
