On the Technology of Heterogenization of Transition Metal Catalysts towards the Synthetic Applications in Ionic Liquid Matrix
With the invention of ionic liquids, synthetic chemistry reached a new arena towards the transition metal catalyzed reactions in the syntheses of fine, specialty, agricultural, commodity, fragrant chemicals and building blocks. Inside the ionic liquid matrix, the transition metal catalysts, when immobilized, offer a valuable solution in terms of heterogenization. This technology offers high level of recyclability without loss of activity and improves the turnover number with high selectivity. Synthetic chemists, chemical engineers and technologists continue their efforts to recover and recycle the transition metal catalysts through various methodologies to convert the processes cost effective. The processes that are reported in the literature reveals that the ionic liquids by virtue of their inertness coupled with ability to retain the catalytic materials provide an excellent solution in terms of high levels of recovery and recyclability. This chapter presents a short account on the recent development in the transition metal catalyzed reactions in ionic liquid systems where both the solvent and the catalyst were recycled and reused without any emission of volatile materials.
