N2 - On the Formation of 1,1,2,3‐Tetrachloro‐2,3‐diethoxycyclopropane in Phase Transfer Catalysed Dichlorocyclopropanations When phase transfer catalysed dichlorocyclopropanations are performed in commercial chloroform as reagent/solvent (50% aq. NaOH/TEBA‐Cl, 40°C), the title compound 4 (a single stereoisomer assumed to be trans) is produced from the ethanol present in chloroform as a stabiliser. Formation of 4 can be avoided by pre‐extracting the chloroform with water. A reaction path for the formation of 4 is proposed. Copyright © 1985 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
