摘要：

The reaction products of C2H3I, n-C3H7I, i-C3H7I, ClCH2I, and Cl(CH2)3I adsorbed on Ag(111) at 100 K have been examined by using temperature-programmed desorption (TPD). All the molecules dissociate thermally on Ag(111) producing surface hydrocarbon fragments and halogen atoms. The hydrocarbon fragments recombine and desorb as higher hydrocarbons below room temperature; they do not dehydrogenate. Surface Cl and I desorb as AgCl and I, respectively, above 700 K. The desorbing hydorcarbon products are 1,3-butadiene for C2H3I, n-hexane for n-C3H7I, 2,3-dimethylbutane for i-C3H7I, ethylene for ClCH2I, and cyclopropane for Cl(CH2)3I.
