A kinetic study has been conducted on the reaction of (arylthio)trimethylstannanes with 1-aryl-1-bromoethanes.The reaction of the arylbromoethane bearing an electron-donating substituent was found involving unimolecular ionization of the arylbromoethane.The other reactions, however, were found to be second-order reactions.The nature of the second-order reactions was shifted from one involving unimolecular ionization as the minor process, to a clear bimolecular nucleophilic reaction, according to the electron-withdrawing nature of the substituents on the arylbromoethanes.

A metal-free procedure for the synthesis of thioethers is described via the base-promoted reductive coupling of tosylhydrazones with thiols through an insertion of a carbene into the S-H bond.
