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.
