Article abstract of DOI:10.1021/jo00295a008

The 5,6-arene oxide of 3,3',4,4'-tetrachlorobiphenyl was prepared by a sequence in which two of the double bonds were introduced by decarboxylations.The first involved a Barton decarboxylative selenation and selenoxide elimination, the second a decarboxyl
