title: Preservation of epoxy groups on surfaces in the covalent attachment of butadiene monoxide on Si(111)-(7×7): the effect of a vinyl substituent.
abstract: Adsorption of butadiene monoxide on Si(111)-(7×7) has been scrutinized by high-resolution electron energy loss spectroscopy (HREELS), scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. The experimental results indicate that surface reaction occurs through a [2+2]-like cycloaddition, which is further supported by the DFT studies.
