Charge-Transfer Complex Promoted Regiospecific C?N Bond Cleavage of Vicinal Tertiary Diamines

A catalyst-free, charge-transfer complex promoted coupling of sulfonyl chlorides with vicinal tertiary diamines to generate sulfonamides is presented. Mechanistic studies showed that these reactions are proceeded via charge transfer of vicinal tertiary diamines to sulfonyl chlorides, forming the unstable sulfonyl quaternary ammonium like complexes which induced the regiospecific intramolecular C?N bond cleavage of vicinal tertiary diamines. (Figure presented.).

An approach to C-N activation: Coupling of arenesulfonyl hydrazides and arenesulfonyl chlorides with: Tert -amines via a metal-, oxidant- and halogen-free anodic oxidation

tert-Amines were harnessed to afford arenesulfonyl hydrazides and arenesulfonyl chlorides via a metal-, oxidant- and halogen-free electrochemical oxidative coupling in an undivided cell at RT. This environmentally benign approach afforded a wide spectrum of sulfonamides in satisfactory yields using cheap and renewable Pencil Graphite Electrodes (PGEs).

A new method for the synthesis of dinaphtho[1,2-b;2′,1′-d] thiophenes and selenophenes

Naphthalene-1-sulfonic acid dimethylamides were treated with n-BuLi and elemental sulfur or selenium to afford dinaphtho[1,2-b:2′,1′-d] thiophenes and selenophenes, respectively. This is the first example of making two C-S/Se bonds and a C-C bond in a single step at room temperature and also demonstrates a useful method for the synthesis of both thiophenes and selenophenes on naphthalene. In the case of the reactions of elemental selenium, diselenides were also obtained along with dinaphtho[1,2-b:2′,1′-d] selenophenes. The structure of dinaphtho[1,2-b:2′,1′-d]thiophene was characterized by X-ray crystallography as a representative molecule.
