Abstract

Treatment of Cp(2)HfCl(2) with two equivalents of LiNH(2)BH(C(6)F(5))(2) in toluene solution yields Cp(2)Hf{NHBH(C(6)F(5))(2)}, which has been crystallographically characterised. The otherwise base-free [NHBH(C(6)F(5))(2)] complex is stabilised by an agostic interaction.

2. Mononuclear Ti[triple bond]N complexes formed by the facile multiple deprotonation of H3N x B(C6F5)3: the importance of chloride ligands

Author

Anna-Marie, Fuller, William, Clegg, Ross W, Harrington, David L, Hughes, and Simon J, Lancaster

Abstract

The crystalline ion-pair [TiCl(NMe(2))(2)(NMe(2)H)(2)](+)[TiCl(2){NB(C(6)F(5))(3)}(NMe(2)H)(2)](-), in which the anion has a triply bonded nitridoborate ligand, is formed through the multiple activation of H(3)N x B(C(6)F(5))(3) when treated with [Ti(NMe(2))(3)Cl].

Abstract

Facile deprotonation of H3N·B(C6F5)3 with [M(NMe2)4] (M = Zr or Ti) yields the novel amidoborate complexes [Zr(NMe2)3{NH2B(C6F5)3}(HNMe2)] and [Ti(NMe2)3{NH2B(C6F5)3}].

4. Intra- and inter-molecular C-H...F-C and N-H...F-C hydrogen bonding in secondary amine adducts of B(C6F5)3: relevance to key interactions in alkene polymerisation catalysis

Abstract

The reactions between the cyclic sec. amines pyrrolidine and piperidine with B(C6F5)3 yield Lewis acid-base adducts with both intra- and inter-molecular hydrogen bonding interactions between C–H and N–H groups and aryl-fluorines in the solid state.
