Abstract: This paper presents the synthesis of (4-ethoxycarbonylphenyl) methyltriphenylarsonium bromide(1) and its reaction at room temperature with α,β-unsaturated ketones(2a-r) in the two phase system of CH2Cl2-50% NaOH(aq) to afford the substituted cyclopropane derivatives(3a-f), and the yields are fairly good (80-87%). Their structures are ascertained by elemental analysis, 1R,1H NMR, and MS spectrometry.

Key words: Quarternary arsonium salts, Synthesis, Phase transfer, Substituted cyclopropane
