Abstract: A visible-light-promoted aerobic oxyphosphorylation of α-diazoesters and H-phosphine oxides has been developed. Using air as the oxygen source, the reaction proceeded smoothly at room temperature under blue-light irradiation. The α-diazoesters, molecular oxygen, and H-phosphine oxides… read more here.

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: 10.1039/c9gc03629f
Abstract: Potassium tert-butoxide-promoted aerobic oxidation of N-alkyl iminium salts is reported. The reaction is atom-economical and environmentally friendly. Iminium salts derived from isoquinoline, quinoline, phenanthridine, phenanthroline, and phthalazine were successfully transformed into their corresponding unsaturated lactams… read more here.
