Cyclopropanation of styrenes and stilbenes using lithiomethyl trimethylammonium triflate as methylene donor

Abstract

Lithiomethyl trimethylammonium triflate, prepared from tetramethylammonium triflate, cyclopropanates several styrenes and stilbenes with electron-donating and selected electron-withdrawing substituents efficiently. Kinetic data support a stepwise nucleophilic addition-ring closure mechanism for this methylenation.
