SINGLE-ELECTRON TRANSFER INDUCED ELEMENTAL STEPS IN THE TRANSFORMATION OF IODOMALONIC ESTERS AND RELATED CH-ACIDS UNDER SOLID-LIQUID PTC CONDITIONS - PREPARATION OF ELECTROPHILIC CYCLOPROPANES

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.
