Regio-, Stereo-, And Enantioselective Reactions of Carbon Acids Catalyzed by Recoverable Organic Catalysts Bearing Ionic Liquid Moieties (Report‪)‬

INTRODUCTION Environmental protection is the crucial challenge faced by humanity in the 21st century. Progressive environmental pollution has been induced by an accumulation of man-caused factors. Amongst them is the intensive development of chemical industry that increasingly aggravates industrial waste generation [1]. Massive wastage levels that may reach hundreds of tons per a product ton, are particularly evident in those multistep processes in low-tonnage chemistry that produce natural compounds, pharmaceuticals, and plant protectors. Environmental issues of chemistry underlie the chemical research area "green chemistry", which has been vigorously advancing over the last decade [2]. A key objective of green chemistry is the design of efficient chemical processes to ensure complete transformation of starting molecules to the target products and multiple use of auxiliary compounds and materials, including solvents and catalysts. Future chemical processes should be based on selective catalytic methods and nontraditional reaction activation techniques.
