摘要
Intramolecular electrostatic repulsions between the local negative charge on a trifluoromethyl group and that on the ortho position of an aryl moiety of a nucleophile was found to be a controlling factor of the diastereoselectivity in a cyclopropanation reaction, in which the electrostatic repulsion was evaluated quantitatively.
