Durch einen stabilisierten Intermediatkomplex vermittelte Friedel‐Crafts‐Alkylierung auf Oberflächen

Angewandte Chemie, EarlyView.
Einblicke in eine Csp3${\rm C}_{sp^{3}}$‐Csp2${\rm C}_{sp^{2}}$‐Kupplung an Edelmetalloberflächen werden anhand einer oberflächenvermittelten Friedel‐Crafts‐Alkylierung auf Ag(111) gegeben. STM, XPS und DFT‐Rechnungen klären den Reaktionsmechanismus auf Einzelmolekülebene und die Stabilisierung des zentralen Intermediats auf.

On‐Surface Friedel–Crafts Alkylation Through a Stabilized Intermediate Complex

Angewandte Chemie International Edition, EarlyView.
On‐surface Friedel–Crafts alkylation is demonstrated on Ag(111) at the single‐molecule level. STM, XPS, and DFT calculations uncover the reaction mechanism and explain the stabilization of the key intermediate, providing insight into noble‐metal‐surface‐mediated Csp3${\rm C}_{sp^{3}}$─Csp2${\rm C}_{sp^{2}}$ coupling. ABSTRACT The incorporation of sp3${\

Electronic structures of HOPG and stage-2 IBr-GIC studied by angle resolved photoemission [PDF]

, 2006
Angle resolved photoemission spectra (ARPES) of host HOPG and IBr-GIC have been measured at 16 K using hν=122 eV. Both HOPG and IBr-GIC show clear dispersions of upper π band and σ bands derived from C 2s and 2p electrons.
