摘要：
(Chemical Equation Presented) Finding the right pathway: Reaction of isotopomers of ethylene with acetate species (see scheme) adsorbed on a Pd(111) surface in ultrahigh vacuum has shown that vinyl acetate is produced by insertion of ethylene into the acetate species to form an acetoxyethyl intermediate, which decomposes by β-hydride elimination to yield vinyl acetate. © 2005 Wiley-VCH Verlag GmbH & Co.
