THE FORMATION, CRYSTAL AND MOLECULAR STRUCTURES OF BIS(η5-INDENYL)DICARBONYLTITANIUM AND BIS(η5-INDENYL)DICARBONYLZIRCONIUM

Bis(η5-indenyl)dicarbonyltitanium has been produced in 47percent yield by reduction of bis(η5-indenyl)dichlorotitanium with activated aluminum in THF solution under a carbon monoxide atmosphere.Bis(η5-indenyl)dicarbonylzirconium can similarly be prepared in 45 percent yield by the reductive carbonylation of bis(η5-indenyl)dichlorozirconium using activated magnesium turnings.IR spectral evidence has been obtained for the corresponding hafnium analog, although it could not be isolated.Detailed syntheses for the precursors (η5-indenyl)2MCl2 (M = Ti, Zr, Hf) have been developed.Bis(η5-indenyl)dicarbonyltitanium crystallizes in the monoclinic space group C2/c with unit cell parameters a 30.435(8), b 7.357(5), c 28.279(8) Angstroem and β 90.93(5) deg.Refinement of 3530 observed reflections lead to final agreement indices of R = 0.052 and Rw = 0.049.Bis(η5-indenyl)dicarbonylzirconium crystallizes in the monoclinic space group P21/n with unit cell parameters of a 7.288(5), b 14.398(8), c 15.273(7) Angstroem and β 89.84(5) deg.Refinement of 2253 observed reflections lead to final agreement indices of R = 0.049 and Rw = 0.055.

From zirconium to titanium: The effect of the metal in t-butylacrylate photoinitiated polymerisation

We report here the synthesis, photochemistry and photoinitiator activity of some titanocenes (1-4) and compare the results with those obtained for the corresponding zirconocenes (5-8). Analysis of the electronic spectra showed that the energy modulation of the lowest electronic transition, which appears to be LMCT in character, is driven both by the substituent on the cyclopentadienyl moiety and by the metal centre. Furthermore, the excited state resulting from irradiation of the complexes at the wavelength of the LMCT transition undergoes ligand-metal bond dissociation with formation of a radical pair, as evidenced by EPR spectroscopy coupled with spin trapping techniques. All the complexes were very active, compared with known organometallic photoinitiators, for the free-radical photopolymerisation of t-butylacrylate. The titanium complexes 1-4, which can be used with visible light, were more active than the zirconium derivatives 5-8. The better yields in photopolymerisation can be interpreted on the basis of the combined effect of two factors: (i) the photoreactivity of the complexes in solution and (ii) the high persistence of the Ti(III) radical species in solution, which guarantees high concentrations of initiators in the polymerisation process.

Titanium(IV) complexes of the type (C9H7)2Ti(SB)Cl have been synthesised by the reaction of bis(indenyl)titanium(IV) dichloride and bidentate schiff base (SBH) in a 1:1 molar ratio in refluxing tetrahydrofuran in the presence of triethylamine.The new complexes have been characterised on the basis of their elemental analyses, conductance measurements and spectral (IR, 1H NMR and electronic) studies.
