The compounds [η5:σ-Me2A(C9H6) (C2B10H10)] Zr(NMe2)2 (A = C, Si) reacted with CS2, PhCN, CH2=CHCN, nBuNCS, and PhNCO to give the mono-, di-, and triinsertion products, depending upon the substrates. These unsaturated substances inserted exclusively into the Zr-N bonds, and the Zr-C(cage) bond remains intact in all reactions. It is believed that the preference of Zr-N over Zr-C(cage) insertion is governed by steric factors. The metal amide compounds also initiated the polymerization of CH2=CHCN to produce poly(acrylonitrile) and catalyzed the trimerization of PhNCO. On the other hand, they reacted with methyl methacrylate to afford [{η5:σ-Me2A (C9H6)(C2B10H10)} Zr(OCH3)(μ-OCH3)]2 and CH2=C(Me)CONMe2. All insertion products were fully characterized by various spectroscopic data, elemental analyses, and X-ray diffraction studies.
