Olefin Metathesis in the Ionic Liquid 1-Butyl-3-methylimidazolium Hexafluorophosphate Using a Recyclable Ru Catalyst: Remarkable Effect of a Designer Ionic Tag

摘要

Environmental concern associated with chemical synthesis has posed stringent and compeling demands for greener processes, and the development of cost-effective and environmentally benign catalytic systems has become one of the main themes of contemporary synthetic chemistry. In this context, efficient recycling and subsequent reuse of homogeneous catalysts are of prime importance. The recently emerged room-temperature ionic liquids hold great potential in meeting these demands, as evidenced by their increasing popularity as innovative and environmentally benign reaction media as well as their use as new vehicles for the immobilization of transition-metal-based catalysts.
