The optically active cobalt(II) complex, MPAC, has proved to be efficient enantioselective catalyst for the cyclopropanation of styrenes with diazoacetates. The addition of a catalytic amount of N-methylimidazole remarkably accelerated the cyclopropanation reaction to improve both the chemical and optical yields of the product.
