The new ligand L1 [2-[(E)-2,6-diisopropylphenyl-phenyimino]-2H-acenaphthylen-(1E)-ylidene]-(2,4,6-trimethyl-phenyl)-amine was prepared by stepwise addition of 2,6-diisopropylaniline and 2,4,6 trimethylaniline to acenaphthenequinone.

Abstract:

This work discusses the C-H bond activation by transition metal complexes using various computational methods. First, we performed a DFT study of oxidative addition of methane to Ta(OC2H4)3A (where A may act as an ancillary ligand) to understand how A may affect the propensity of the complex to undergo oxidative addition. Among the A groups studied, they can be a Lewis acid (B or Al), a saturated, electron-precise moiety (CH or SiH), a σ-donor (N), or a σ-donor/π-acid (P). By varying A, we seek to understand how changing the electronic properties of A can affect the kinetics and thermodynamics

Abstract:

There has been a growing demand for specific linear alpha olefins in the polyethylene industry in order to control polymer rheology. This growing demand thereby increases the need for highly active and selective ethylene oligomerization catalysts. Chromium-based catalysts continue to be of high interest for this application due to this metal’s versatility in both selective and non selective ethylene oligomerization. Ligand design is an important consideration in oligomerization chemistry: the ability of the ligand to stabilize low valent chromium and to support a two-electron redox process

Abstract:

Catalytic ethylene oligomerization is a well understood industrially viable process. The large majority of scientific literature and patents concerning this process has been developed with the use of chromium catalysts. Commercial systems producing selective tri/tetramerization, non-selective oligomerization and polymerization are all based on this metal with the exception of a few systems based on other transition metals (Zr, Ti, Ni etc.). This versatility raises interesting questions about chromium’s unique behaviour. Essentially, selective or non-selective oligomerization and polymerization

Abstract:

碩士<br>國立彰化師範大學<br>化學系<br>99<br>A series of zirconium and hafnium complexes containing symmetric and asymmetric tridentate substituted pyrrolyl ligand have been synthesizd and characterized. The zirconium compounds Zr[C4H2N(2-CH2NtBu)(5-CH2NMe2)](NR2)2 (4, R = Me；5, R = Et) have been prepared by reacting M(NR2)4(1, M = Zr，R = Me；2, M = Zr，R = Et) with 1 equiv of [C4H2NH(2-CH2NHtBu)(5-CH2NMe2)] in heptane via deamination. MCl[C4H2N(2-CH2NHtBu)(5-CH2NMe2)][C4H2N(2-CH2N-tBu)(5-CH2NMe2)](6, M = Zr；7, M = Hf) have been prepared by reacting M(NEt2)4 (2, M = Zr 3, M = Hf) with 2 equiv of [C4H2NH(2-CH2

Ph.D. (Chemistry)<br>Compounds 3-ferrocenylpyrazole (L1) 3-ferrocenyl-5-methylpyrazole (L2) and 4- ferrocenyl-1-methyl diketone (L7) were synthesized according to literature procedure, while compounds 3-ferrocenylpyrazolyl-methylenepyridine (L3), 3-ferrocenyl-5- methylpyrazolyl-methylenepyridine (L4), 3-ferrocenylpyrazolyl-ethyl amine (L5) and 3- ferrocenyl-5-methylpyrazolyl-ethylamine (L6) were prepared by phase transfer alkylation of the 2,6-bis(bromomethyl)pyridine or 2-bromoethylamine with the appropriate ferrocenylpyrazole L1 or L2 in a 1:1 ratio. These compounds L3-L6 show structural iso

Abstract:

M.Sc.<br>This dissertation deals with the syntheses of tridentate (O^N^N) coordination ligands [{2,4-di-tert-butyl-6-[(2-(3,5-RR-pyrazol-1-yl-ethylimino)-methyl] phenol}, R = H (L1), Me(L2), Ph(L3), t-Bu(L4)], which was reacted initially with MX2 (M = Fe, Co, Ni; X = Cl, Br). The ligands L1-L4 were also modified by functionalizing the phenol group in this ligand group to an ethoxy in L5 and L6 (L5 = [(3,5-di-tert-butyl-2-ethoxy-benzylidene)-[2-(3,5-dimethyl-pyrazol-1-yl)-ethyl]-amine, L6 = [(3,5-di-tert-butyl-2-ethoxy-benzylidene)-[2-(3,5-di-tert-butyl-pyrazol-1-yl)-ethyl]-amine)], or into a p

Abstract:

<p>A series of neutral and cationic group 4 and neutral group 3 model complexes of the Me₂Si(η⁵-C₅H₄)(η⁵-3-(CMe₃)-C₅H₃)(tBuSp) ligand have been prepared: tBuSpZrCl₂(1), tBuSpZr(CH₂SiMe₃)₂ (8), tBuSpZrMe₂ (9), [tBuSpZrH₂]₂ (10), tBuSpZrMeCl (11), tBuSpZrMe(CH₂CMe₃) (12), tBuSpZrMe(CH₂SiMe₃) (13), tBuSpScCl(THF) (14), tBuSpScCH(SiMe₃)₂ (17), [tBuSpScH] (18), and tBuSpTiCl₂ (19). The kinetically preferred isomers of 12 and 13 have been identified, and in both cases the syn isomer is preferred. We have obtained solid state structures of [tBuSpZrH₂]₂ (10), tBuSpZrMeCl (11), tBuSpZrMe(CH₂CMe₃) (1
