Functional Hybrids from Graphenes and Small as well as Large Molecules


The interactions of graphene on the one hand, and solid substrates and molecular adsorbates on the other, may be relatively weak. Yet, they alter each other’s properties significantly, if brought into close proximity, such as in layered hybrid structures. Quite generally, the very first molecular adlayer in these hybrids exhibits different structural and dynamical properties than subsequent layers. Also the electronic and optical coupling of the hybrids is significant, being strongly determined by near-field effects. Examples are surfactants and macromolecules such as ds-DNA adsorbed from solutions into controlled conformations to supported graphenes. Another one is a flexible, molecularly thin slit pore, formed by a hydrophilic solid substrate and graphene, which can be filled with water, dyes and macromolecules. The potential for applications in opto-electronics and for analytical sciences will be discussed.

Underutilized Functional Groups as Tools for Discovery


Our group uses allenes as tools for exploring important issues in contemporary organic synthesis.  For example, our efforts to develop new allene amination methods led to the discovery of silver complexes capable of catalyst-controlled and tunable chemoselective C-N bond-forming reactions.  The ability of silver to adopt a multitude of different coordination geometries allowed us to extend this chemoselectivity to favor reaction at one site of unsaturation over another, to choose between amination of a C-H or a C=C bond or even tune for reactivity between two C-H bonds.  Allenes have also proven to be powerful platforms for accessing an array of aminated building blocks for the construction of bioactive molecules. Our efforts in developing highly regio-, chemo- and stereocontrolled allene aziridination methods for the preparation of libraries of densely functionalized aminocyclitols and other complex amines related to pactamycin and jogyamycin will be described.

Transition Metal-Catalyzed Methods for Introducing Heteroatoms into Hydrocarbon Frameworks


Several new methods for introducing heteroatoms into hydrocarbon frameworks using transition metal catalysis will be discussed. This will include efforts towards developing palladium-catalyzed silyl-Heck reactions for preparing unsaturated organosilanes from simple alkenes. In addition, new alkylation strategies for nitroalkanes and primary amides using copper catalysis will be described.
