Reactivity of group 4 benzamidinate complexes towards mono- and bis-substituted silanes and 1,5-hexadiene

Zirconium and titanium bis(benzamidinate) dimethyl complexes were found to be active catalytic precursors for the oligomerization of mono- and bis-substituted silanes. The activation of such complexes, by an excess of MAO or by an equimolar amount of B(C

2 and (PPh4)2*2CH2Cl2; Syntheses, IR Spectra, and Crystal Structures

2 has been prepared by the reaction of the amidinato complex 2 with sodium fluoride in acetonitrile suspension, as well as by the reaction of ZrCl4 in acetonitrile, both in the presence of 15-crown-5.On an analogous route (PPh4)2*2CH2Cl2 has been prepared by the reaction of 2 with PPh4Cl in CH2Cl2 solution, as well as by the reaction of ZrCl4 with PPh4Cl in CH2Cl2.The compounds are characterized by their IR spectra and by crystal structure determinations. 2: Space group P21/a, Z = 4, 6589 observed independent reflexions, R = 0.069.Lattice dimensions at 20 deg C: a = 1705.0(9), b = 1092.4(6), c = 1906.5(10) pm, β = 113.14(3) deg. 2 forms ion triples, in which both sodium ions are seven-coordinate by five oxygen atoms of the crown ether molecules, as well as by a fluorine and a chlorine atom of the cis-(2-) unit. (PPh4)2*2CH2Cl2: Space group P, Z = 1, 4831 observed independent reflexions, R = 0.041.Lattice dimensions at 20 deg C: a = 1030.1(5), b = 1124.8(6), c = 1245.6(6) pm, α = 70.81(3), β = 80.61(4), γ = 80.39(4) deg.The compound has an ionic structure with ZrCl6(2-) ions of symmetry Ci. - Keywords: Halogeno-Zirconates(IV), Syntheses, IR Spectra, Crystal Structure
