Synthesis and basic characteristics of segmented poly(arylene ether sulfone)-poly(arylate) copolymers
… the segmented copolymers with high poly(arylate) contents. The morphology of the copolymers was found to be totally amorphous for those capolymers with low levels of the poly(arylates). They were semicrystalline when the poly(arylate) contents were increased beyond a critical value of …

Liquid crystalline multi-block copolymers
… the anisotropic segment is based on a rigid poly(arylate) moiety. The difunctionally terminated, controlled molecular weight poly(sulfone) oligomers were synthesized via a nucleophilic aromatic substitution reaction. Functional end groups included phenolic, acetate and carboxyl. The structure and …

I: Catalytic Direct C-H Arylation of Pyrazoles. II: Toward Modulation of Neuroplasticity with Small Molecules
… and the ability to sequentially and selectively arylate specific positions on the azole core to rapidly access highly substituted pyrazoles will be discussed. Part II of this thesis addresses two separate targets to modulate neuroplasticity. In Chapter 2, the TrkB receptor as a potential target …

Cysteine arylation
… complementary approaches are developed to arylate cysteine thiol. First, through a nucleophilic aromatic substitution (SNAr) mechanism, fluorinated aromatic reagents are used for the regioselective arylation of a single cysteine in the presence of many. An enzyme-tag pair (glutathione …

Investigations into cyclopropanation and ethylene polymerization via salicylaldiminato copper (II) complexes
Two distinct overall research objectives are in this Master’s thesis. Very little relates the two chapters apart from the ligands. The first chapter addresses diastereoselective homogeneous copper catalyzed cyclopropanation reactions. Cyclopropanation of styrene and ethyl diazoacetate (EDA) is a …
