The reaction of butenes caused by the surface compounds formed from SO<SUB>2</SUB> on Mg(OH)<SUB>2</SUB> or MgO has been studied. It has been shown that the cis-trans isomerization of 2-butene is selectively induced by the sulfur compounds. This specific isomerization has been explained by the previously proposed mechanism that the reaction is accompanied by the copolymerization of 2-butene and SO<SUB>2</SUB>. The infrared spectroscopic study on the sulfur compounds formed on Mg(OH)<SUB>2</SUB> or on MgO has demonstrated the presence of SO<SUB>3</SUB><SUP>2−</SUP>, SO<SUB>4</SUB><SUP>2−</SUP>, or sulfinato complexes. The formation of these surface species may cause a strong electrostatic field on the surface, resulting in the polarization of reactant molecules, which is necessary for the initiation of the copolymerization or of the cis-trans isomerization. It has been shown, however, that the presence of weakly adsorbed SO<SUB>2</SUB> is essential for determining the catalytic activities of the solids in the SO<SUB>2</SUB>-induced isomerization.
