, p. 10971 - 10974 (2018)
The palladium-catalyzed oxidative preparation of dibenzothiophene derivatives from 2-biphenylyl disulfides by C?H functionalization is described herein. This procedure shows a high tolerance toward various functional groups and does not require the further addition of a metal oxidant, a base, or a ligand. Also, the present method was applied to the facile preparation of dibenzoselenophene.

An approach for the synthesis of selenaheterocycles starting from aryl diazonium salts was developed. The one-pot process and subsequent visible-light-mediated silver-catalyzed cyclization enabled the synthesis of selenaheterocycles in the absence of a photocatalyst. The reactions were carried out under mild conditions without the use of toxic or sensitive reagents. (Figure presented.).
Mo-Based Oxidizers as Powerful Tools for the Synthesis of Thia- and Selenaheterocycles

A highly efficient synthetic protocol for the synthesis of thia- and selenaheterocycles has been developed. By employing a MoCl5-mediated intramolecular dehydrogenative coupling reaction, a broad variety of structural motifs was isolated in yields up to 94 %. The electrophilic key transformation is tolerated by several labile moieties like halides and tertiary alkyl groups. Due to the use of disulfide or diselenide precursors, a high atom efficiency was achieved.
