Book Description
Electrochemical alkene diazidation offers an attractive strategy towards vicinal diamines due to the mild reaction conditions offered by oxidative electrochemistry and facile azide N3 to NH2 reduction methodologies. The electrochemical oxidation of TEMPO in the presence of N3- and an alkene was shown to electrochemically form azidooxygenated products alongside minor amounts of diazide. Diazide product formation was amplified alongside azidooxygenation suppression through the synthesis of a sterically congested catalyst CHAMPO. CHAMPO was able to successfully catalyze the formation of diazides across a variety of alkene types and substrates featuring oxidatively sensitive functional groups. Organometallic catalysts offer an alternative route to carbon heteroatom bond formation as unlike purely organic catalysts, the multiple oxidation states accessible through redox manipulation of a metal center allows access to otherwise inaccessible reaction paradigms. Carbazole-based PNP pincer complexes of Co were synthesized and reacted with RN3 to furnish Co-imidos (Co=NR) which have been invoked as key intermediates in C-H amination and C=C aziridination. Upon full characterization, the competency of Co=NR towards C-N bond formation was investigated. A second generation PNP pincer complex was synthesized to incorporate binding of a main-group metal with the hypothesis that transition metal main-group cooperativity would allow for activation and binding of ligands atypical for monometallic systems. Heterobimetallic systems of E-TM (E = Gallium and Indium, M = Cobalt and Nickel) were synthesized and characterized using SXRD and their activity towards Nitrogen oxyanion (NO3- and (NO2-) binding was investigated.

Book Description
Modern Inorganic Synthetic Chemistry, Second Edition captures, in five distinct sections, the latest advancements in inorganic synthetic chemistry, providing materials chemists, chemical engineers, and materials scientists with a valuable reference source to help them advance their research efforts and achieve breakthroughs. Section one includes six chapters centering on synthetic chemistry under specific conditions, such as high-temperature, low-temperature and cryogenic, hydrothermal and solvothermal, high-pressure, photochemical and fusion conditions. Section two focuses on the synthesis and related chemistry problems of highly distinct categories of inorganic compounds, including superheavy elements, coordination compounds and coordination polymers, cluster compounds, organometallic compounds, inorganic polymers, and nonstoichiometric compounds. Section three elaborates on the synthetic chemistry of five important classes of inorganic functional materials, namely, ordered porous materials, carbon materials, advanced ceramic materials, host-guest materials, and hierarchically structured materials. Section four consists of four chapters where the synthesis of functional inorganic aggregates is discussed, giving special attention to the growth of single crystals, assembly of nanomaterials, and preparation of amorphous materials and membranes. The new edition's biggest highlight is Section five where the frontier in inorganic synthetic chemistry is reviewed by focusing on biomimetic synthesis and rationally designed synthesis. - Focuses on the chemistry of inorganic synthesis, assembly, and organization of wide-ranging inorganic systems - Covers all major methodologies of inorganic synthesis - Provides state-of-the-art synthetic methods - Includes real examples in the organization of complex inorganic functional materials - Contains more than 4000 references that are all highly reflective of the latest advancement in inorganic synthetic chemistry - Presents a comprehensive coverage of the key issues involved in modern inorganic synthetic chemistry as written by experts in the field
