Abstract
A tetrachlorobiphenylene was isolated from a SO2Cl2-biphenylene reaction mixture by reversed-phase liquid chromatography. The structural assignment of 2,3,6,7-tetrachloro-biphenylene is based on data from the synthesis route, gas chromatography/mass spectrometry, and nuclear magnetic resonance longitudinal relaxation studies. The UV photolysis of octachlorobiphenylene (OCBP) produced a mixture of tetra through octachlorobiphenylenes which provided a standard to assess the retention times of biphenylenes relative to PCDDs and PCDFs. The recoveries of the biphenylenes through the adipose tissue cleanup procedures developed for PCDDs and PCDFs ranged from 62-92%. Composite extracts from control and exposed groups were analyzed by NCI mass spectrometry and no peaks characteristic of biphenylenes were found.
