Abstract:

This thesis explores the synthesis and the reactivity of novel amidine salts resulting from various N-methylformamides and N-methylbenzamides I and II. Treatment of these compounds with triflic anhydride under mild conditions led to extremely facile alkyl transfer from an sp3-hybridised nitrogen centre to very weakly nucleophilic triflate anions. For the reaction pathway of substrates III and VII, in silico studies propose an equilibrium between the more stable tetrahedral triflate intermediate IV and the superelectrophilic amidinium disalt V from which dealkylation takes place.

Abstract:

Mixed alkyllithium / lithium alkoxide aggregates in the form (RLi)n(ROLi)m were formed by addition of corresponding alcohol compounds at different Li/O ratios. Variable temperature 13C and 6Li NMR spectroscopy were used to verify the formation of the mixed aggregates and to study their behavior in hydrocarbon solution. Spectra for the lithium n-propoxide / n-propyllithium and iso-butyllithium / lithium iso-butoxide systems each indicated at least one mixed aggregate.

Abstract Thirty phosphane ligands were prepared and characterized. Aryl groups of the phosphane ligands were modified through change in functionality. The side chains were the following: trifluoromethylphenyl, selenomethylphenyl, 9-anthryl, alkyl-substituted aryl groups, and pyridyl and alkyl groups. In addition, three chromium carbonyl complexes of potentially bidentate arylphosphanes containing nitrogen heteroatoms were prepared and characterized. Characterization of the isolated complexes verified the monodentate coordination from phosphorus and two bidentate coordination modes, (P,N)-bound

Abstract:

Transition-metal-catalyzed cross-coupling reactions are reliable tools for forging C–C bonds. The Engle Lab has previously pioneered the intermolecular difunctionalization of unactivated alkenes facilitated by nickel catalysis, where regioselectivity is controlled through the use of a bidentate directing group. A limitation of existing methods is that allyl groups have not yet been successfully incorporated, as the electrophile scope has been limited to alkyl and aryl species. Fundamentally, C–C p-bonds have served as key building blocks for the assembly of complex molecules, and the ability t

Our research is to synthesis the polypyrrole with alkyl chains on nitrogen site and carbon site and observe the effects. We observe the phase transition by X-ray and DSC. But it is hrad to observe because of its absorbing light. Between observing, we just can find the liguid crystal transition on the polypyrrole with octadecane alkyl side chain on nitrogen site. Besides, we can find the 2.8Å and 3.2Å peaks By shearing and solvent casting. Such a phenomenon is common in conj

The experimental result showed that these surfactants exhibited excellent surface-active properties including surface tension, wetting power, emulsification stabilized and possessed lowly foaming and foam stabilized, In the alkyl chain length from fatty acid(8,10) the surface-activities increase with the increase of alkyl chain length in the molecules, whil

Abstract:

As levels of carbon dioxide continue to increase in the atmosphere, it is appealing to consider the prospect of utilizing CO2 as a C1 building block for the synthesis of value-added organic chemicals. Such transformations offer potential to directly counteract environmental concerns, and could also enhance the recyclability of current materials. To meet this challenge, the development of metal catalysts capable of promoting the functionalization of carbon dioxide is necessary. Furthermore, there is great interest in employing main group metals for these transformations, particularly those meta

The main strategy is D-π-A structure, the diphenylamine for electron donor, phenyl and conjugated moiety for electron bridge, with cyanoacetic acid for acceptor. Besides, to confirm the retarding of charge combination from electrolyte, the alkyl-functionalized groups were joined like norbornane、cyclohexane in modified group for the function of steric hindrance. All of these compounds were characterized by UV/VIS spectrophotometer, fluorescence spectrophotometer and

Abstract:

碩士<br>國立中山大學<br>化學系研究所<br>88<br>Abstract The reactivity and bonding of allyl groups (C3H5) on a Ag(111) surface have been investigated under ultrahigh vacuum conditions by temperature-programmed reaction/desorption (TPR/D) and reflection-adsorption infrared spectroscopy (RAIRS). The atomically clean surface was achieved by Ar+ sputtering and verified by AES. The surface crystallinity was assured by LEED. Surface -bound allyl groups were generated by dissociative adsorption of allyl halides. Our study shows that the C-X (X= I or Cl) bond can be ruptured below 200K to render adsorbed allyl
