Heterogenization of solvent-ligated copper(II) complexes on poly(4-vinylpyridine) for the catalytic cyclopropanation of olefins

[Cu(NCCH3)6][B(C6F5)4]2 and [Cu(NCCH3)6][B{C6H3(CF3)2}4]2 are immobilized on poly(4-vinylpyridine). Both resulting materials (Cu(II) complexes immobilized on polymer) are applicable as catalysts for the cyclopropanation of olefins at room temperature. The immobilized Cu(II) compounds are quite stable and recyclable for several catalytic runs, however with some decrease in the catalytic activity.
