Interactions of Light with Organic Chromophores: A Photochemical and Photophysical Investigation
(North Dakota State University, 2018)
Over the past century, light has emerged as a useful tool finding utility in various fields such as device fabrication, the medical field, as well as utility as an energy source. Chemist have adopted this abundant energy ...
Late Transition Metal-Catalyst Development for Alkyne Coupling Reactions
(North Dakota State University, 2016)
Alkynes are versatile and valuable synthetic precursors in a variety of organic
transformations and have found tremendous applications in materials science and pharmaceutical
chemistry. In recent years, there has been a ...
Stereospecific Photochemical Transformations Involving Axially Chiral Acrylanilides and a-Oxoamides
(North Dakota State University, 2013)
Asymmetric photochemical transformations have been under-explored due to the ineffectiveness of conventional methodologies/reagents/catalysts (point chiral auxiliaries and inductors) that were generally employed for thermal ...
New Strategies for Ruthenium Catalyzed C-C Bond Formation
(North Dakota State University, 2014)
Transition metal-catalyzed C-H bond activation allows direct functionalization of the ubiquitous C-H bonds in organic molecules to increase the molecular complexity. Since Murai's pioneering work in ruthenium catalyzed ...
Novel Asymmetric Approaches for Construction of Small Molecules by Cyclization and Cycloaddition
(North Dakota State University, 2015)
Development of novel asymmetric and catalytic methods for synthesizing small organic
molecules containing hindered quaternary and tertiary centers is a major challenge and a
dynamic area of investigation in synthetic organic ...
Visible Light Photocatalysis of N-N Bond Based Compounds
(North Dakota State University, 2016)
The well-established principles of organic photochemistry, offer chemists the fundamental understanding and tools for studying light induced chemical transformations. Employing visible light for photocatalysis, one can ...
Stereospecific Phototransformations of Atropisomeric Chromophores
(North Dakota State University, 2014)
Photochemical transformations are unique strategy in synthesis that enables us to
access complex and structurally diverse organic scaffolds. However, the challenges in controlling
the excited-state to perform stereoselective ...
Achiral Templates in Asymmetric Catalysis: Applications in Construction of All Carbon Quaternary Centers
(North Dakota State University, 2018)
Conjugated olefins are readily available and inexpensive starting materials and their functionalization offers a rapid access to many important building blocks for organic synthesis. The functionalization of these olefins ...
Exploitation of Biomass for Applications in Sustainable Materials Science
(North Dakota State University, 2019)
Biorefinery may be defined as the process of accessing chemical commodities from living systems; consequently, biomass becomes the antecedent for renewable resources through biorefinery. Advantages to this process over ...
Synthesis of Precursors to Non-isocyanate Polyurethanes
(North Dakota State University, 2018)
Biobased diamines are excellent precursors for the synthesis of non-isocyanate polyurethanes (NIPUs). We have prepared several biobased diamines using three different reactions for their synthesis. In the first method, we ...
