Project Abstract

The development of asymmetric methodologies is one of the fundamental research areas in chemistry. The ability to selectively prepare the target chiral molecule of choice is a worthwhile goal. This project investigates methods to develop environmentally friendly asymmetric technologies by; 1) Determining impact of established catalysts 2) Utilizing low toxicity, biodegradable, task specific solvents 3) Improved chiral catalyst design 4) Developing biodegradable organocatalysts 5) Studying reactions which generate less waste 6) Applying magnetic nanoparticles supported chiral catalysts, for simplified recycling. This work combines green chemistry and nanotechnology with toxicology and biodegradation studies and represents a new joint DCU/TCD initiative. Organocatalysis offers an exceptionally attractive green chemistry methodology to industry. However with their toxicity and eco(toxicity) still undetermined there still is concern over possible persistence in the environment, aquatic toxicity and health risks. Firstly, this study will identify both toxic organocatalysts and ionic liquid solvents and help assist environmental policy/decision makers to raise concern over these examples. Secondly non-toxic, biodegradable alternatives will be prepared, including an investigation of magnetic nanoparticle supported biodegradable organocatalysts. A database of the (eco)toxicity data collected for the organocatalysts and ionic liquids will be made available through the EPA and project website to supplement the publication of the work.
