Abstract

The syntheses of complexes [Mo(?5-C5H 5)-{?4-C4(CF3) 4}(CO)I] and [Mo(?5-C5H5) {?4-C4(CF3)4}-S 2CNMe2] containing a tetrakis(trifluoromethyl) cyclobutadiene ring are described, variable temperature 19F n m r studies reveal the existence of high barriers to rotation of the C4 ring about the metal-ligand axis in both complexes.
