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.

Palladium(II)-Catalyzed Synthesis of Dibenzothiophenes from 2-Biphenylyl Disulfides by C?H Functionalization

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.

THERMAL REACTIVITY OF 4'SUBSTITUTED- AND 4'-SUBSTITUTED-2-PHENYL-BENZENESUPHENANILIDES

The thermal decomposition of 4'-nitro, 4'-H, and 4'-methoxy-benzenesulphenanilides in benzene and/or furan, and of 4'-substituted-2-phenylbenzenesulphenanilides ( 1d-1f ) in benzene, was found to proceed by two distinct pathways: ( i ) nucleophilic displacement by furan and/or another sulphenanilide unit and ( ii ) homolytic S-N bond fission to give sulphenyl and anilino radicals.An increase in the electron-withdrawning capability of the 4'-substituted favours the ionic pathway, whwreas the radical pathway is favoured by an increase in the reaction temperature.
