Reaction Between Tetraallylmolybdenum and Hydroxylated Fe(100) in Ultrahigh-Vacuum - A New Route to Characterizable Mixed-Metal Oxide Catalyst Models
Single crystal Fe(100) was hydroxylated to give a p(2x1) overlayer. Tetraallylmolybdenum, (eta3-allyl)4Mo, reacted with Fe(100)-OH to give surface bound (allyl),Mo which was examined by high-resolution electron energy loss spectroscopy (HREELS). The surface-bound complex maintains eta3-allylic ligation, in contrast to what is observed for the depostion of (eta3-allyl)4Mo onto silica. Subsequent hydrogenation and oxygenation were followed by HREELS and Auger electron spectroscopy, and surface bound Fe-O-Mo and Mo=O units were identified.
