Host: Professor Joseph Topczewski

The Neufeldt Lab studies transition metal-catalyzed reactions of organic compounds. In particular, we explore strategies for using catalysts to induce molecules to react in novel ways. This research includes catalyst design to invert the conventional selectivity of cross coupling reactions, to functionalize hydrocarbons, or to enable other novel transformations. We especially value mechanistic understanding, and we use both experimental and computational (DFT) tools to gather insight into the origin of novel selectivity and reactivity in our catalytic systems.

Abstract

An Environmental Chemist's View of Biodegradable Plastics

Contamination of the environment with plastic is a long-recognized problem, but in recent years, there has been a remarkable increase in public attention and outcry regarding plastic pollution. The low cost and durability of plastic materials, which make them desirable for many applications, are the same factors that contribute to their accumulation. The low cost lowers the barrier to short-term and single use applications and the durability means that, once in the environment, these materials are highly persistent. On this latter point, there is a growing interest and market for non-persistent, biodegradable plastic materials, which could help the problem of accumulation of plastic in the environment. This presentation will focus on several key questions about these alternative biodegradable materials: How do we know that a material is really biodegrading instead of just breaking down into microplastic? How does the receiving environment affect biodegradability? Are there applications where biodegradable plastics are viable alternatives to conventional plastics? What are the challenges that we face from an environmental chemistry perspective?

Millipore Sigma Seminar
Professor Christopher Douglas
Department of Chemistry
University of Minnesota
Host: Professor Nicholas Race

Research in Professor Christopher Douglas' group focuses on the development of new synthetic methods and on finding solutions to a variety of synthesis problems. Our program in developing new methods is particularly focused on reactions we feel have the potential to change the way scientists approach the construction of organic molecules. For example, development of carbon–carbon sigma bond activation could open up unusual disconnections in retrosynthetic analysis, leading to new or more efficient syntheses of desirable molecules. We are also interested in new approaches to conjugated systems applicable in organic electronics, particularly the linear acenes including derivatives of tetracene, pentacene, and polyacene, a long-sought polymer. Our interest in synthesis extends well beyond organic electronics to encompass biologically relevant compounds.
