Abstract

We investigated the adsorption states of 2-methylpropene and propene on Si(100)c(4x2) using low-temperature scanning tunneling microscopy. We have found that regioselective cycloaddition reactions (di-σ bond formation) occur between the asymmetric alkene molecules and the asymmetric dimers on Si-(100)c(4x2). First-principles calculations have elucidated that the regioselectivity is closely related to the structures of precursor species and these precursor species have carbocation-like features. Thus, we conclude that Markovnikov's rule is applicable for the cycloaddition of asymmetric alkene with the asymmetric dimer on Si(100)c(4x2).
