Alkenes undergo smooth cyclopropanation with ethyl diazoacetate using a catalytic amount of rhodium acetate dimer, Rh 2 (OAc) 4 , immobilized in the air-and moisture-stable 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid, [bmim]PF 6 , to afford cyclopropanecarboxylates in excellent yiel
