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 oc cur during the transformation of iodomalonic esters and related CH-aci ds to cyclopropane derivatives under solid-liquid phase transfer catal ytic conditions. The iodo derivatives are formed from iodine and CH-ac ids ''in situ'', in the same pot in which the transformations to cyclo propane derivatives take place. A number of electrophilic cyclopropane s with a wide range of substituents have been synthetised by this rout e.
