Abstract:

Thesis advisor: James P. Morken<br>This dissertation will describe the development of three transition metal-catalyzed syntheses of nonracemic organoboronates. The first chapter explains the development of a palladium-catalyzed enantiotopic-group-selective cross-coupling of geminal bis(boronates) with alkenyl electrophiles. This process enables the synthesis of highly valuable nonracemic disubstituted allylic boronates. Chapter two describes a palladium-induced 1,2-metallate rearrangement of vinylboron “ate” complexes. The newly developed process incorporates an alternative route for the trans

The first detailed study of the palladium-catalyzed amination of aryl nonaflates is reported. Use of bulky electron-rich monophosphinobiaryl ligands or BINAP allow for the catalytic amination of electron-rich and -neutral aryl nonaflates with both primary and secondary amines. Using XantPhos, the catalytic amination of a variety of functionalized aryl nonaflates resulted in excellent yields of anilines; even 2-carboxymethyl aryl nonaflate is effective

Abstract:

Palladium-catalyzed reactions for carbon-carbon bond formation have had a significant impact on the field of organic chemistry in recent decades. Illustrative is the 2010 Nobel Prize, awarded for “palladium-catalyzed cross couplings in organic synthesis”, and the numerous applications of these transformations in industrial settings. This thesis describes recent developments in C(sp2)-C(sp3) bond formation, focusing on alkane arylation reactions and arylative dearomatization transformations. In the first part, our contributions to the development of intramolecular C(sp3)-H arylation reactions

Abstract:

碩士<br>國立成功大學<br>化學系碩博士班<br>96<br>Recently we found several highly substituted naphthalenes 37 have been synthesized in one pot by treatment of arenes 38 with alkynes 35 in the presence of palladium acetate and silver acetate. In this Pd-catalyzed protocol, an arene provides a "benzo" unit to construct a naphthalene core via a two-fold aryl C�{H bond activation. To the best of our knowledge, this is the first example of preparation of naphthalenes from two-fold of aryl C�{H bond activations. We have optimized the reaction conditions and tested various arenes from the preparation of such mol

碩士<br>中原大學<br>化學研究所<br>101<br>The purpose of this research is to study the chemoselectivity of intramolecular nitrene insertion of sulfamate ester catalyzed by PdCo (OAc) 4 which was synthesized from Pd(OAc) 2 and Co(OAc) 2. In this study, sulfamate ester compounds 9-13 were used as reactants, for the PdCo(OAc)4 catalyzed amination reaction of C-H bond. The chemoselectivity was analyzed from the product distribution of resulting oxathiazinane compounds.

The source of diphenylphosphine oxide has to be added rather slowly by Syringe Pump (KDS100) to achieve the goal. The crystal structure of 3a was determined by X-ray crystal diffraction methods. Indeed, the phosphination took place at the ortho-position of interannular ring. A reaction mechanism is proposed

Abstract:

To address the issue of unnecessary functional group transformations in synthesis, the direct functionalization of carbon-hydrogen (C―H) bonds presents itself as an efficient and atom economical process. In particular, palladium(II)-catalyzed oxidative functionalization of arene C–H bonds were investigated to yield intermolecular and intramolecular arylations. Kinetic studies and characterization of bimetallic palladium(II) complexes led to the discovery of two other palladium(II)-catalyzed processes: arene hydroxylation and selective chlorination of anilides.

The distribution of products 3 and 4 was greatly depending on the electron-withdrawing or -donating capacity of the substituent on the amido-fragment of 1. The carbazole derivatives 4 were obtained when the substituent is electron-withdrawing group. While the substituent is electron-donating group, it trends to form secondary phosphine oxides substituted products 3. Both 3_eaaa and 4_eaa were obtained while the substi

Silver nitrate and tert-butanol were proved to be the best oxidant and solvent for the process, respectively. The product yields fluctuated from modest to excellent, and the reaction showed sufficient functional group tolerance. p-Benzoquinone served as an important ligand for the transmetalation and reductive elimination steps in the cata
