Abstract

The iron(III)-promoted synthesis of densely-substituted 4H-chalcogenchromene from organochalcogen propargylamines in the presence of diaryl dichalcogenides is reported. Subsequent C2-functionalization with electrophiles and potassium trifluoroborate salts via Suzuki-Miyaura coupling reaction are also presented. A plausible mechanism based on HRMS experiments is proposed and discussed. (AU)
