Kowsari Keywords Copper chromite spinel nanoparticles Basic ionic liquid (±)-Trans-2- phenylcyclopropanecarboxylic acid Trans-cinnamic acid Cyclopropanation Introduction Ionic liquids (ILs) are organic salts with low melting points and negligible vapor pressures . Ionic liquids have polar characteristics and are excellent media to hold polar species such as transition-metal catalysts [2–5], and so they have been used for the immobilization of homogeneous catalysts [6, 7]. The application of ILs in catalysis has been increasing due to their ability as solvents for many transition metal-catalyzed reactions . The IL phase efﬁciently induces catalyst immobi- lization and has a low miscibility with organic reaction products; as a consequence, liquid–liquid biphasic processes using ILs incorporating transition metal catalysts have been widely examined . Functional nanoparticles have also been synthesized using ionic liquids [10, 11]. The use of metal nanocatalysts and
