[structure: see text] The viability of the Diels-Alder (DA) cycloaddition of conjugated dienes onto the sidewalls of single-wall carbon nanotubes is assessed by means of a two-layered ONIOM(B3LYP/6-31G:AM1) approach. Whereas the DA reaction of 1,3-butadiene on the sidewall of an armchair (5,5) nanotube is found to be unfavorable, the cycloaddition of(More)
The 1,3-dipolar cycloadditions (1,3-DCs) of a series of 1,3-dipolar molecules onto the C(100)-2 x 1 surface have been investigated by means of hybrid density functional B3LYP method in combination with cluster model approach. It was found that 1,3-DCs on the C(100)-2 x 1 surface are more favorable over their molecular analogues both thermodynamically and(More)
The chemisorption and decomposition of thiophene (C4H4S) and furan (C4H4O) on the reconstructed Si(100)-2 × 1 surface has been investigated by means of the hybrid density functional (B3LYP) method in combination with a cluster model approach. Two chemisorption mechanisms, i.e., [4 + 2] and [2 + 2] cycloadditions of C4H4X (X ) S,O) onto a surface dimer site,(More)
The viability of 1,3-dipolar cycloadditions of a series of 1,3-dipolar molecules (azomethine ylide, ozone, nitrone, nitrile imine, nitrile ylide, nitrile oxide, diazomethane, and methyl azide) onto the sidewalls of carbon nanotubes has been assessed theoretically by means of a two-layered ONIOM approach. The theoretical calculations predict the following:(More)
