Abstract:

This study focuses on the antimicrobial activity of Cu(II) complexes of some orthohydroxybenzaldimines and its derivatives. Four different categories of Schiff base ligands were prepared by condensing salicylaldehyde, o-vanillin, p-vanillin and vanillin with p- and osubstituted anilines; 1-aminonaphthalene; 2- and 3-aminopyridine; 2- and 3- aminomethylpyridine as well as 2-aminobenzimidazole. The last category was prepared from ophenylenediamine and o-vanillin.

Single-Molecule Magnets (SMMs) are discrete molecules that exhibit slow relaxation of magnetization. Unlike conventional magnets that rely on the long range magnetic ordering in the form of domains, these molecules act as magnets independently, that is without the influence of neighbouring molecules. SMMs have intrigued physicists and chemists alike for over twenty years with their potential future applications in data storage quantum computing, and with this communal interest there has been significant collaboration between the two fields of research. SMMs have brought forth an opportunity fo

A systematic practical method to prepare highly chi (χ)-constrained amino acids has been developed.

With an increase of the size of R² from H to Me to Et to i-Bu, the reactivities of the alkyl bromides decreased. The starting Schiff bases had more effective stereocontrol at the α-carbon center than at the β-carbon center. The starting Schiff bases showed differential reactivity toward the racemic electr

Abstract:

Ferrocenyl monochalcone was prepared by reacting monoacetyl ferrocene with benzaldehyde and characterized by FTIR and NMR spectroscopy. Ferrocenyl monochalcone was reacted with hydrazine hydrate to form three products. The major orange product has been spectroscopically characterized as ferrocenyl pyrazoline derivative. Cyclopentadienyl manganese tricarbonyl compound was acetylated and reacted with salicylal hydrazide to obtain schiff base compound of acetylcymantrene. The compound was characterized by FTIR,1NMR and CHN analysis.

碩士<br>國立中興大學<br>化學系<br>93<br>本論文嘗試以苯丙胺酸與纈胺酸當起始物，合成單手性三牙配位基(S)-43~(S)-49及三牙配位基50。使用配位基(S)-44與二乙基氯基鋁可形成錯化合物57，由X-ray單晶繞射解析鑑定金屬中心為扭曲的四角錐結構，而錯化合物53及59則是以氫光譜判定結構。使用三牙單手性配位基與二乙基溴基乙醚鋁對不同烯酮進行三乙基鋁不對稱1,4共軛加成反應，本論文探討催化反應可能影響的因素，包含反應溶劑、溫度、催化劑當量數、加成試劑當量數及不同取代基之起始物。研究結果顯示，以配位基(S)-43在乙氰溶劑下，對查耳酮進行反應，其產物可得到45%的產率及69%的鏡像超越值。另外也使用不同取代基之配位基，對查耳酮進行三乙基鋁加成反應，其中以配位基(S)-43在二氯甲烷為溶劑下，可得到1,2加成產物且選擇性高達98%。

Abstract:

A series of five, tetradentate Schiff-base ligands were synthesised and chelated to vanadyl to form oxovanadium(IV) complexes. The ligands, 4,4’-{benzene-1,2-diylbis[nitrilo(1E)phen-1-yl-1ylidene]}- dibenzene-1,3-diol (H2L1), 4,4’-{ethane-1,2-diylbis[nitrilo(1E)phenyl-1-yl-1-ylidene]}dibenzene-1,3-diol (H2L2), 4,4’-{propane-1,2-diylbis[nitrilo(1E)phen-1-yl-1-ylidene]}dibenzene-1,3-diol (H2L3), 4,4’-{(2- hydroxypropane-1,3-diyl)bis[nitrilo(1E)phen-1-yl-1-ylidene]}dibenzene-1,3-diol (H2L4) and 4,4’-{2,2- dimethylpropane-1,3-diyl)bis-[nitrilo(1E)phen-1-yl-1-ylidene]}-dibenzene-1,3-diol (H2L5), ch
