Chemical synthesis green chemistry research

This book describes green chemistry approaches that employ liquid or supercritical carbon dioxide. Supercritical fluids have been investigated for more than a century however, applications to chemical synthesis and materials processing are relatively new. Since the 1990s, we have witnessed a veritable explosion of increased research activity in the area of chemical reactions and processes in liquid or supercritical carbon dioxide with the... 

The concept of Green Chemistry was introduced in the early 1990s in the USA. After the introduction of the US Pollution Prevention Act, the Office of Pollution Prevention and Toxics (OPPT) explored the idea of developing new or improved chemical processes to decrease hazardous to human health and the environment. In 1991, OPPT launched a research grants program called Alternative Synthetic Pathways for Pollution Prevention. This program was focused on pollution prevention in the design and synthesis of chemicals. 

There are quite a few less common heteronnclei, particularly in Elementorganic Chemistry, with highly important applications in catalysis, C—C and C—N bond forming reactions. Medicinal Chemistry, Pharmacy, Green Chemistry and natnral product synthesis, to name a few, that would make studying their NMR spectroscopy highly beneficial to that part of the chemical community that occupies itself with the research, production, and distribution of these chemicals. 

Much of the research effort relevant to Green Chemistry has focused on chemical manufacturing processes. Here we can think of Green Chemistry as directing us towards the ideal synthesis (Fig. 1.1-7) [3, 15].
