Synthesis of new hybrid 1,4-thiazinyl-1,2,3-dithiazolyl radicals via Smiles rearrangement

2017

The condensation reaction of 2-aminobenzenethiols and 3-aminopyrazinethiols with 2-amino-6-fluoro-N-methylpyridinium triflate afforded thioether derivatives that were found to undergo Smiles rearrangement and cyclocondensation with sulphur monochloride to yield new hybrid 1,4-thiazine-1,2,3-dithiazolylium cations. The synthesized cations were readily reduced to the corresponding stable neutral radicals with spin densities delocalized over both 1,4-thiazinyl and 1,2,3-dithiazolyl moieties. peerReviewed

An Unusual Ditelluride: Synthesis and Molecular and Electronic Structures of the Dimer of the Tellurium-Centered Radical [TePiPr2NiPr2PTe]•

2005

Facile formation of the ditelluride [(TePiPr2NiPr2PTe-)2], which exists as a centrosymmetric dimer (see picture: Te green, P purple, N blue, C gray) with a weak Te[BOND]Te bond, embodies a new feature of the chemistry of dichalcogenoimidodiphosphinate ligands. The monotelluride HPiPr2NiPr2PTe analogue is obtained as the P[BOND]H tautomer. peerReviewed
