Nickel mediated sulfur–selenium and sulfur–sulfur bond formation
Abstract
Electrophilic addition of the PhSeCl to a nickel dithiolate yields S,S′-bis(phenylselenenyl-N,N′-bis(mercaptoethyl)-1,5-diazacyclooctane nickel(II) dichloride and a dimeric, intermolecular bis-disulfide which results from ligand oxidation.
