Versatile synthetic processes in aqueous media: Trends and future prospects

Abstract

Some aspects of green process chemistry are summarized in the context of water (H2O) as a key solvent component in the catalytic transformations. We first learn characteristic nature of water and its importance in scalable synthetic operation. Next, emphasis has been placed on such chemical reactions in the presence of PTC catalyst, transition metal catalyst and water itself as a key reagent. The progress will be made in the near future by the utilization of green catalytic reactions with full control of the products and wastes, strongly guided by the statements of Anastas (the 12 principles of green chemistry).
