In our previous study of the reaction of 1,2-diphenylethane (bibenzyl), DPE, and other compounds with D{sub 2} at temperatures to 450{degrees}C and pressures of 2000 psi in isolation from metal surfaces, we were able to provide strong evidence for a mechanistic scheme wherein radicals formed by the homolysis of weak bonds, react with D{sub 2} to give D atoms. These participate in short radical-chain processes responsible for hydrocracking and exchange of H for D at unsubstituted aromatic positions. In contrast to the simple thermolysis of DPE wherein stilbene (PhCH=CHPh), STH, is formed as a major product, the reaction of DPE with D{sub 2} produces relatively small amounts of this compound. Moreover, the mole % of STB among the products decreases as conversion increases, indicating that initially produced STB is consumed. It, therefore, seemed important to examine the reaction of STB with D{sub 2}. This study has subsequently been extended to other unsaturated compounds and the results are reported below.
