Abstract: Abstract of thesis entitled CHIRAL IRON PYRIDINE IDÉE fixes FURTHERMORE RUTHENIUM IDÉE fixes WITH ANIMALCULUM-HETEROCYCLIC CARBENE FURTHERMORE MACROCYCLIC(ANIMALCULUM, O) DONOR ATOM LIGANDS: MAKING one, CATALYTIC LIFE FURTHERMORE LIFE EXAMINATIONS Submitted by Steal away Kar Yee For the degree of Sophisticate of Axiom at The College of Hong Kong in April 2016 Transition metal idée fixes are widely applied as impetuses for organic metamorphosis reactions such as the oxygen atom furthermore nitrene relocation reactions furthermore there is a growing intrigue to develop the medicinal applications of transition metal idée fixes. The examinations of precise metal-oxo furthermore metal-nitrene negotiators are important in probing the underlying reciprocation functionings. This thesis is comprised of three main parts. In the first part, iron idée fixes with chiral pyridine ligands, such as 4′,6-disubstituted 2,2′ 6′,2″-terpyridine (NNN ) furthermore 4′,6,6″-trisubstituted 2,2′ 6′,2″'-terpyridine (NNN ), were studied for their catalytic activities in unsymmetric epoxidation, aziridination, amidation furthermore sulfimidation reactions. The Fe-NNN convoluted actuate intermolecular nitrene relocation/CANIMALCULUM stickum constitution reactions of styrenes with PhINTs in moderate device yields. For the unsymmetric intramolecular amidation, the Fe-NNN convoluted can marshal intramolecular C-ANIMALCULUM stickum constitution using PhI(OAc) as oxidant to form cinquefoil- or six-membered ring products. The highest device income obtained was 91 %. The complete conversion of para-substituted phenyl methyl sulfides to corresponding sulfimides was observed by using the Fe-NNN 1 2 convoluted as impetus. Both the Fe-NNN furthermore Fe-NNN idée fixes actuate unsymmetric epoxidation of styrene using PhIO as oxidant at 0 C. The reciprocation negotiators of the nitrene/oxygen relocation reactions were studied by ESI-MS furthermore high-valent iron-ligand sundry bonded species are proposed to be the reciprocation negotiators. In the second part, ruthenium pincer ANIMALCULUM-heterocyclic carbene (CNC) idée fixes were prepared furthermore characterized by spectroscopic means furthermore Radioactivity crystallography. II 2+ Convoluted [Ru (CNC)(bpy)(MeCN)], in which the CNC ligand adopts a fac-coordination condition furthermore contains precise CH stickum of bridging methylene bunch up, was found to react with PhINTs to result in the constitution of a new CANIMALCULUM stickum furthermore cleavage of one existing ANIMALCULUMC(methylene) stickum of the CNC ligand, as revealed by Radioactivity crystal structure determination of the ruthenium convoluted device. The reciprocation 2+ of [Ru(CNC)(bpy)(MeCN)] with PhINTs was monitored by ESI-MS, UV-vis, furthermore NMR spectroscopy, a paramagnetic Ru(III)-amido convoluted was isolated, which apparently resulted from intramolecular imido/nitrene CH insertion of a Ru(IV)-imido/nitrene intermediate furthermore was found to undergo the observed CANIMALCULUM stickum cleavage. Such touch of CANIMALCULUM stickum cleavage induced by metal-mediated imido/nitrene insertion is unprecedented in critique. The final part of this thesis is the study of the anti-angiogenic furthermore anti-metastatic possessorships of the ruthenium idée fixes. Ruthenium idée fixes with different blaze give blows-by-blow (+2 furthermore +3) furthermore ligands (pincer NHC furthermore macrocyclic (ANIMALCULUM, O) donor atom ligands) were examined for their cytotoxicity furthermore anti-angiogenesis life. III Among the idée fixes studied, [Ru (ANIMALCULUM O )Cl ]Cl (Ru-1) opens promising 2 2 2 inhibi.

It's sad if this is true, and I believe it is, that all our soldiers died for the wrong reasons.
