Converting n‑Alkanol to Conjugated Polyenal on Cu(110) Surface at Mild Temperature

Achieving C­(sp3)–H activation at a mild temperature is of great importance from both scientific and technologic points of view. Herein, on the basis of the on-surface synthesis strategy, we report the significant reduction of the C­(sp3)–H activation barrier, which results in the full C­(sp3)–H to...

Description
Summary:Achieving C­(sp3)–H activation at a mild temperature is of great importance from both scientific and technologic points of view. Herein, on the basis of the on-surface synthesis strategy, we report the significant reduction of the C­(sp3)–H activation barrier, which results in the full C­(sp3)–H to C­(sp2)–H transformation of n-alkanol (octacosan-1-ol) at a mild temperature as low as 350 K on the Cu(110) surface, yielding the conjugated polyenal (octacosa-tridecaenal) as the final product. The reaction mechanism is revealed by the combined scanning tunneling microscope, density functional theory, and synchrotron radiation photoemission spectroscopy.
