Cyclohexanes dihalo

It was characterized by chemical analysis, ozonolysis to form formaldehyde, hydrogenation, bromination and by its infrared and 1H-NMR spectra. The diene has also been prepared by pyrolysis of l,4-bis-(acetoxymethyl)cyclohexane (13,14), from cyclohexanedione by the Wittig reaction (11,15) or by reaction with diazomethane (16), and by the electrochemical or metal reduction of 1,4-dihalo-bicyclo-[2,2,2-]octanes (17,18) or of l,l,2,2-tetrakis-(bromo-methyl)-cyclobutane (19). It is very stable if stored in ammonia rinsed, dry flasks.
