The generation of bromine by oxidation of bromide anions at the anode and reduction of molecular oxygen at the cathode to hydrogen peroxide resulted in the overall formation of two molecules of Br2 (=four electron oxidation) by passing just two electrons through the solution. The bromine was used for the bromination of alkenes and thereby a linear paired electrolysis was attained which resulted in

3-t-butylcyclohexene with iodine and potassium thiocyanate are examined. The action of iodine and thiocyanogen with (E)-hex-3-ene gives different results from those reported in the literature. Isomerizations of the vic-iodothiocyanates to vic-iodoisothiocyanates and formation of 2-alkoxy-2-thiazolines from the latter adducts are reported.
