Single electron transfer induced elemental steps have been shown to occur during the transformation of iodomalonic esters and related CH-acids to cyclopropane derivatives under solid-liquid phase transfer catalytic conditions. The iodo derivatives are formed from iodine and CH-acids "in situ", in the same pot in which the transformations to cyclopropane derivatives take place. A number of electrophilic cyclopropanes with a wide range of substituents have been synthetised by this route.
