Compounds of the formula ##STR1## in which Het represents an optionally substituted aromatic heterocycle having a sulphur or oxygen hetero atom and attached via a ring carbon atom, and X is halogen, alkyl, alkaryl, cyano, alkoxy, mono- or di-alkylamino, acyloxy or aryl, are useful intermediates to a range of cyclopropane derivatives. Processes for their preparation and their use in further synthetic processes are also described.
