Synthesis and Structure Determination of 8- and 9-iodocamphorquinone Bis(ethylene ketal)

Abstract

The structures of 8-and 9-iodocamphorquinone bis(ethylene ketal) have been confirmed by spectroscopic and single crystal X-ray analysis. The unexpected formation of the latter isomer is attributed to intramolecular rearrangement of the camphor skeleton, the mechanistic details of which have been explored using coset analysis.
