Cycloaddition Chemistry at Surfaces:  Reaction of Alkenes with the Diamond(001)-2 × 1 Surface

Covalent modification of graphitic carbon substrates by non-electrochemical methods

“…The authors outline several possibilities based on mechanisms proposed for thermal reactions of similar species at diamond [68,69,70] and silicon [71,72] surfaces, and the earlier work of Mazur and Murray, who proposed that surface carbon radicals form when carbon substrates are heated under vacuum or are abraded in the absence of air [29,30]. Figures 7-9 depict possible reaction pathways.…”

Atomic structure of steps and defects on the clean diamond (100)-2×1 surface studied using ultrahigh vacuum scanning tunneling microscopy

“…1 The diamond (100)-2 ϫ1 surface is reactive, and has been investigated as a substrate for metal films, 4 buckyballs, 5 functionalized organic molecules, 6 and mechanosynthesis of nanostructures. 7 To our knowledge, the atomic structure of steps and defects on the diamond (100)-2ϫ1 surface has not been reported.…”

Cycloaddition reaction of furan with Si(100)-2×1

“…The reactive sticking probability is approximately unity on Si͑100͒, 0.1 on Ge͑100͒, and ϳ10 Ϫ3 on C͑100͒. 24 The difference in reactivity is attributed to the various extent of dimer buckling on these surfaces. SivSi and GevGe dimers can tilt out of the surface plane, shown in Fig.…”

“…Hamers et al 24,25 and Bent et al 26,27 extensively investigated the cycloaddition reaction mechanism of cyclopentene and other unsaturated hydrocarbons on Si͑100͒, Ge͑100͒, and C͑100͒. The reactivity of cyclopentene was found to be very different on these three crystals.…”
