Stereoisomeric 1,2,4,6,7,9-hexaoxecan derivatives from dimerisation of a 1,2,4-trioxolan; stereospecific interconversion
Abstract
Carbon disulphide and other acceptors catalyse the dimerisation of the endoperoxide formed from photo-oxygenation of 1,3-diphenylisobenzofuran to mixtures of four stereoisomeric diperoxides; pairs of these dimers are stereospecifically interconvertible on gentle heating.
