Abstract

Cyclopropanation of styrene with ethyl diazoacetate catalyzed by Pd(II) in ionic liquid [omim][BF~4~] was investigated. Palladium catalysts can be effectively immobilized in ionic liquid. The catalysts PdCl~2~ and cyclopalladated complex 2 contained in ionic liquid could be recycled for 6 and 7 times, respectively, without losing the efficiency.
