Abstract

A triphenylarsine-catalyzed one-pot procedure for the preparation of cis-cyclopropanes with acyclic electron-deficient olefins with carbonyl-stabilized arsonium ylides formed from methyl bromoacetate or phenacyl bromide in the presence of NaHCO3 has been achieved. This method is simple, high-yielding and cis-selective. The success of this method depends on the choice of base, solvent and temperature.
